Question about performance statistics

• I have several questions about performance in XP that I asked about

  I have maybe something to do with my pc which has caused several issues that I have been asking questions on this site and have yet to get solved. Maybe it's a matter of slow internet access or an intermittent problem of internet access or a busy RAM which caused these problems for me:

  • 7 + 1 end Nows to Log Off or restart
  • IE cannot display the website (goes and load when I click Refresh!)
  • Enter the network password
  • Scrolling mouse (sometimes) when I click on a link in an e-mail or on a website or open a new tab opens to the blank page
  • Yahoo Messenger which is set to autostart in the Journal, sometimes impossible to display the weather plugin and so I just click on the v Options above and select Reset to Default height and it then displays to fill this place and it is currently running. What can I do to speed up my slow sometimes Tablet?
  • What can I do to speed up my slow sometimes Tablet?

  My Internet Explorer works fine, almost all the time and only question #2 or #4 occasionally and not very often. I need to put right at the front here saying that this isn't a malware problem and it is not a lack of program updates. If you could help me with this, just read my profile since these two are discussed in depth in my profile. I recently did a clean install and I visit unwanted websites on the internet and not much at all and I have installed Security Essentials immediately and it updates every day on its own. Also, I've updated all my programs and drivers manually and my operating system as much as possible by using Windows Update in custom update high priority mode (optional) software & hardware (optional). And I use File Hippo at each connection to find updates of programs that are available and I used another program to search for driver updates.

  I was unable to find information about malicious programs in your profile. Malware is STILL a possibility. ALWAYS. You run MBAM?

  Must you Yahoo Messenger runs at startup? (I doubt it). Plug-ins are also known to cause problems. If your plugin weather might be screwing things up.

  You have never set up a clean boot?

  Finally, you should never connect, I pointed out repeatedly. Reset must be a rare event, too.

• question about performance optimization

  Hi friends,
  
  In our project, according to the changes of condition, a developer has changed its select query.
  This query uses essentially most of the rows in a table
  (consider table_a with col1, col_2, col_3, and col_4 using oracle 10 g DB
  Col_1 is PK).
  
  The query will in a manner similar to this.

  create or replace package pkg_sample is 
     type ref_cur is ref cursor;
     procedure proc_ex(
        p_col_2   table_a.col_2%type,
        p_col_3   table_a.col_3%type,
        p_col_4   table_a.col_4%type,
        o_result   ref_cur);
  end pkg_sample;
  
  create or replace package body pkg_sample is 
     procedure proc_ex(
        p_col_2   table_a.col_2%type,
        p_col_3   table_a.col_3%type,
        p_col_4   table_a.col_4%type,
        o_result   ref_cur) is 
     begin
        open o_result for
           select *
           from   table_a
           where col_2 = p_col_2
           and     nvl(col_3, 'A') = nvl(p_col_3,'A')
           and     nvl(col_4, 'A') = nvl(p_col_4,'A');
     exception 
        when others then 
           raise;
     end proc_ex;
  end pkg_sample;

  Now, I have a question regarding the use of NVL on both sides of the select query.
  
  As our request includes not PK, its doing a table scan on the entire table full.
  
  Now, we can create a function based index... do we need to have indications for each combination? (i.e. when the col_2 is not null and col_3 is null, etc...)
  
  It don't you guys think, we can use NVL on both sides or is it possible to write the select query for maximum performance?
  
  Thank you
  Jack

  instead of NVL, I would use this:

  and   (a.col2 = b.col2
         or (a.col2 is null and b.col2 is null)
        )
  

  This way, you avoid conflicts with the coded hard 'a '.

• Question about performance.

  Hello

  So I have a mbpr 15 "end 2013
  2.6 i7 quad
  16 gb 1600 mhz

  Gforce NIVIDA 750 (2 GB gpu)

  Update on everything

  I use 2 Dell u2515H on full resolution as resolution 2560 x 1440, the macbook is in clamshellmode, and I connect just like this
  1 TB to a thunderbolt dock

  1 TB as displayport towards each other.

  My macbook is running like crazy fans and I do nothing, I tried to adjust the 1080 displays or something less, but fans are always warping.

  My old macbook pro could run two screens with no problems, the fans only hit when I started working.

  Surely the gpu should be able to handle this.

  And Yes, I plug in the charger, connect the thunderbolts and then press my keyboard to go real clamshell.

  Any help would be received with joy.

  The best
  Johannes Drakenberg

  It may be a question if this is normal or not.  Install a temperature/speed control application.  When this phenomenon occurs, post a picture of the temperature/fan speed.

  You could also run some Diagnostics of Apple:

  Meeting in a bar in engineering of the Apple store for a FREE evaluation is also a good option.

• Question about changing the refresh frequency for the perf of run-time statistics

  Hello

  I would like to know if there is no API or refresh rate of orders to change the provider.

  For example when I train to recover PerfProviderSummary.getRefreshRate () disk performance statistics, I see that the refresh rate is set at 20 seconds (by default). Call of PerfProviderSummary.setRefreshRate (5) has no effect on future calls and the refresh rate remains at 20 seconds.

  ESXTOP however to change the refresh rate up to 2 seconds.

  Thank you and best regards,

  Prashanth

  Hi Julie,.

  It is not possible to change the frequency of refresh in real time of 20 seconds. The vim. PerformanceManager interface is limited to a minimum of 20 seconds sampling period.

  In addition, it is always recommended to call the QueryPerfProviderSummary API on the entity to verify the refresh rate and use this query for performance statistics refresh rate.

  I hope this answers your concern!

• Can question about a possible question, I do it my way?  The end result really me the measure of success?

  I have a question about a theoretical question of the VCAP (specifically the example below).  I could do it is a flash by going directly to the host instead of using the stinking vMA and resxtop, I've always will mark the full points by my way?

  "

  Scenario 11

  < Return | Next >

  Scenario:

  On a specific host of ESXi, a set of virtual machines is not good. You intend to determine the root cause. To do this, you want to collect usage data of resources at a level more granular than vSphere Client performance graphs can provide.

  Requirements:

  • Use resxtop to collect all the statistics for 2 minutes every 3 seconds.
  • Export the data to a CSV file called results.csv.
  • Import the results.csv file in the Windows performance monitor.
  • Use Windows performance monitor to indicate the time of CPU ready for all the virtual machines on the 2 minute period.

  Environmental information:

  • ESXi host: Home - 01.lab.local

  I'm under the impression that it was some sort of bug, fixed now, thanks to you guys useful...

  urgent vMA, would appreciate your help VCAP is tomorrow.

  Always extremely frustrating in the circumstances

• Satellite A350D - 20K - Question about upgrade second HDD + Temperature

  I have a question about my laptop. I have notticed it is a second location of HARD disk on the bottom.
  Is it possible to use this to increase my storage?
  And if yes, how do I do that? I don't see all the connectors.
  What type of HARD drive to use in case it is possible to use this slot machine?

  My second question is on my laptop to be very hot after a short period of use.
  I installed speedfan to record the temperature. When I start the laptop, it already is between 45 and 50 degrees.
  He stayed there for half an hour and then it starts to get warmer. When I start to use the laptop for anything, it triggers to between 70 and 80 degrees.

  This does not seem normal to me. I tried to clean the vents with compressed air, but it has not made a difference.
  I searched on the internet how to take the laptop part for proparly cleaned TI.
  But I can't so I'm looking that destroy it.

  This could be the cause and more importantly, how can I solve this problem?

  Tom

  The second HARD drive bay contains the HARD drive connectors?
  If Yes, then you can use a SATA 2.5 HARD.
  If there are no connectors, then you will not be able to use the second HARD drive

  > I have installed speedfan to record the temperature. When I start the laptop, it already is between 45 and 50 degrees. He stayed there for half an hour and then it starts to get warmer. When I start to use the laptop for anything, it triggers to between 70 and 80 degrees.

  CPU and GPU produce a lot of heat. The heat dissipation is always created then there s nothing unusual that the temperature rose to higher level.
  You can change the settings in Win 7 power management. You can set the CPU to lower performance and can increase the activity of fan, which will help lower the temperature.

• Question about temperature internal Satellite A300 ND1

  Hello

  I have a question about the temperature of the standards it of ok for my laptop and what is the normal temperature and how can I keep it low?

  Thank you.

  Hello

  It's not easy to say what a normal temperature could be.
  The temperature is not always the same and it depends on the use of the laptop.
  Usually, the temperature would increase while gaming or running applications high performance. Why? Because all devices such as the CPU and GPU would focus the heat dissipation and this leads to a higher temperature.

  > How can I keep it low
  Very simply, you can keep still low level, but you can make sure there is enough free space around the laptop to ensure good air circulation.
  Also don t use the laptop on your knees etc in order do not obstruct cooling fans.

  It s also advised to clean the fans from time to time using the jet of compressed air. These sprays are really useful and could buy in the stores of different computers.

• Satellite U405D - several questions about overheating/disassembly/upgrading etc.

  Hello

  I have several questions about my old one by Satellite U405D-S2910

  1. when it works, after 2-3 hours (I run usually small programs such as safari, msn messenger and bsplayer) CPU gets 85 to 90 C (178-188). When I play age of Empires 2 (come on, its an old game) like 2-3 hours, it stops. What could be the possible reason? Furthermore, let me inform you about the climate of the city I live, 30 c temperature - humidity 25-35% (today).
  PS. CPU is AMD Turion 64 X 2 Dual-Core Mobile Processor. Model RM-74

  2. I'm going to disassemble my laptop in order to clean its cooling units (I think at the rate of overheating is this). It does seem like a desktop computer, so complicated. Ive seen a disassembly not to not (btw, its so difficult to spell dismantling :) I think Im going to do this. What are your suggestions on this subject? experiences could help me?

  3. my laptops is Ram 2x2gb PC5300 DDR2 667 MHz SDRAM memory, I want to replace RAM memory 2x2gb MACH XTREME DDR2 1333 MHZ CL9 NOTEBOOK. Should I do it? Fit my portable, stable work? any suggestions?
  PS. motherboard chipset AMD M780V

  4 - Finally :), should I use OS 64 - bit or 32-bit OS (win7)? what OS would you use if you were me?

  Thank you.

  Hey Buddy,

  1 + 2. I think everything is related to a higher internal temperature and you must clean your laptop using a jet of compressed air. That is why it s not necessary to remove, just blow softly and soon the air through the laptop. You can buy such compressed air which squirts of each computer store I think and it takes only 5 minutes.
  You can find a useful article about this here:

  3. in my opinion he should forget this update! The speed of the RAM is related to the FSB of the CPU and as much as I know about Satellite U405D it s 667 MHz so it s already the RAM faster than you can have. Save your money and buy a larger HARD drive or in the best case a SSD that can really improve the performance!

  4. in my view, the answer is clear: Windows 7 64-bit.
  Only a 64-bit OS supports full 4 GB of RAM. ;)

• A few questions about Toshiab reocvery disk for Satellite P300-133

  Hello guys,.
  I had a few questions about unpleasant surprises of recovery:

  (* 1) * I just make recovery DVD using Toshiba Recovery Disk Creator and he asked initially for 2 DVDs - but when one has been done it does not require a second blank DVD. Is it possible all the Windows Vista system files to write on 1 DVD?

  (* 2) * if I could reinstall Windows Vista using recovery of HARD drive option (by pressing F8) without using the recovery DVD?

  (* 3) * HARD drive partitions that will be formatted (just system C: or C: and E :) using HARD drive recovery?

  (* 4) * what is DVD - Image of the hard drives or the installation of Vista recovery files?

  Its pretty bad idea to not include BONES on DVD when I paid for it.
  Thanks for all the Toshiba problems :(

  1. I think the recovery disk creator means 2 CDs. I also have a Portege M700 with Windows Vista and a DVD. I got it and after that, I have a clean install of Vista with all the drivers and tools of Toshiba. Nothing is missing.

  2. Yes, you can reinstall Vista using recovery of HARD drive option when you press F8 at startup. You don't need the recovery DVDs, but you should create a when your HARD drive get some errors or something else. If you need a new recovery DVDs, you paid for one.

  3 HARD drive and complete partitions will be formatted, so backup your data first on a DVD disk external DRIVE, USB stick or something else.
  After the reinstallation, you have factory settings.

  4. the recovery DVDs is an image of the HARD disk on the factory settings. If you perform a recovery, there are all the drivers and tools are already installed. Of course, on the disk are files of installations of Vista, but you can use this DVD on your Satellite P300. The disc cannot be used on another Satellite or on a PC.

  If you have any other questions, take a look in the user manual. There are a number in the formations of the recovery. It s in Chapter 3.

• Ask questions about the functionality of EA8500 MU-MIMO

  Dear Linksys

  I bought EA8500, and it arrived today.

  I have two questions about the functionality of MU-MIMO of EA8500 AP.

  1. I want to compare the performance between SU-MIMO and MU-MIMO, but there is no option to control this feature in the router admin page. Is that one of the possible ways?

  2 EA8500 supports 1733 Mbps wireless speed, but it resembles the speed of 1 Gbps ethernet cable.

  This router supports really speed 1 Gbps ethernet? or y at - it an option to support more throughput as the aggregation of links?

  Thank you

  Hi, hyeonu. For your first query, it is not possible because there is no option to disable the feature of MU-MIMO on your Linksys EA8500 router. In addition, with regard to your second, you can get a higher throughput of 1 Gbps since this is the maximum capacity of your ethernet connection.

• Questions about discussions...

  Hello

  I have a new app to do that requires network access.

  I have read this EXCELLENT post from peter_strange:

  http://supportforums.BlackBerry.com/T5/Java-development/connecting-your-BlackBerry-http-and-socket-c...

  Because I can't use BIS - B because I'm not a partner of the Alliance, I wanted to take a look at the new OS 5.0 network API and see how it works.

  I know that network connections should be performed in a separate thread.

  I'm far from being an experienced Blackberry developer... so I have a few questions about discussions.  I looked around the Internet, read on the forum, read the documentation, did some tests and so far, I came up with this code:

  SerializableAttribute public class HTTPConnection extends UiApplication {}
  Public Shared Sub main (String [] args) {}
  HTTPConnection PAP = new HTTPConnection();
  theApp.enterEventDispatcher ();
  }

  public HTTPConnection() {}
  pushScreen (new HTTPConnectionScreen());
  }
  }

  class HTTPConnectionScreen extends form {}
  public HTTPConnectionScreen() {}
  setTitle ("HTTPConnection");
  Add (new RichTextField ("choose a type of connection :"));

  final RadioButtonGroup = new RadioButtonGroup() rbGroup;
  RadioButtonField radioButtonF1 = new RadioButtonField ("Direct TCP", rbGroup, false);
  RadioButtonField radioButtonF2 = new RadioButtonField ("WAP 1.0/1.1", rbGroup, false);
  RadioButtonField radioButtonF3 = new RadioButtonField ("WAP 2.0", rbGroup, false);
  RadioButtonField radioButtonF4 is new RadioButtonField ("BES/MDS", rbGroup, false);.
  RadioButtonField radioButtonF5 = new RadioButtonField ("BIS-B", rbGroup, false);
  RadioButtonField radioButtonF6 = new RadioButtonField ("WiFi", rbGroup, false);
  Add (radioButtonF1); Add (radioButtonF2); Add (radioButtonF3); Add (radioButtonF4); Add (radioButtonF5); Add (radioButtonF6);
           
  FieldChangeListener listener = new FieldChangeListener() {}
  ' Public Sub fieldChanged (field field, int context) {}
  ConnectionThread ct = new ConnectionThread (rbGroup.getSelectedIndex () + 1);
  CT. Start();
  }
  };
           
  ButtonField buttonField = new ButtonField ("Connect", ButtonField.CONSUME_CLICK);
  buttonField.setChangeListener (listener);
  Add (buttonField);
  }

  / * method of onSavePrompt override default to avoid being asked if I want to record every time * /.
  protected boolean onSavePrompt() {}
  Returns true;
  }
  }

  class ConnectionThread extends Thread {}
  private int transportType;
  public ConnectionThread (int n) {}
  transportType = tt;
  }
      
  public void run() {}
  ConnectionFactory connFact = new ConnectionFactory();
  ConnectionDescriptor connDesc = connFact.getConnection ("URL", transportType, null);
  If (connDesc! = null) {}
  try {}
  HttpConnection httpConn = (HttpConnection) connDesc.getConnection ();
  httpConn.setRequestMethod (HttpConnection.POST);
  httpConn.setRequestProperty ("Content-Type", "application/x-www-formulaires-urlencoded");
  OutputStream out = httpConn.openOutputStream ();
  out. Write (Integer.ToString (transportType). GetBytes());
  int responseCode = httpConn.getResponseCode ();
  If (responseCode == HttpConnection.HTTP_OK) {}
  UiApplication.getUiApplication () .invokeLater (new Runnable() {}
  public void run() {}
  Dialog.Alert ("- SUCCESSFUL CONNECTION-");
  }
  });
  }
  If (httpConn! = null) httpConn.close ();
  } catch (IOException e) {}
  System.Err.println ("IOException Caught:" + e.getMessage ());
  }
  }
  }
  }

  In fact, this code works very well... but I want to improve it, and I have a few questions:

  1. I think that right now, every time I click on the 'Connect' button, I start a new thread. I would like to end this thread in the "run" method, but I don't really know how to access the variable 'ct' from there.   Counsel on how to do it?  Or maybe always use the same thread until my application is closed?

  2. in the FieldChangeListener of my "Submit" button, I want to access the value of radio box.  I did work, but I had to do my 'final' variable  What is the right way to do it?

  3 - to display a dialog box with 'Successful connection', I just wanted to write something in my main screen.  How I do that?

  I'm just a bit confused as to just what set up when you use a separate thread.

  Thanks for your advice!

  Edit: Hidden URL I connect to...

  That's what I call a good question! (now I'm wondering why the forums do not work with opera correctly, in any case, here my baldy to the answer format): 1. your thread "dies" when it's over, no need to close it. 2 Yes 3. You can use a reminder. See for example http://www.javaworld.com/javaworld/javatips/jw-javatip10.html

• Question about the differences in commands

  Hey guys -.

  I just had a few questions about the differences between orders that seem to perform the same function.  Can you let me know if an order is more preferable to the other and what the difference is.  I would really appreciate it as it I currently practice some INE laboratories and I see that orders change from lab to lab.  Thanks advance!

  1. When you write a static NAT for specific host 1 - is - this important if I understand the 32 subnet?

  EX: static (inside, outside) 1.1.1.1, 2.2.2.2 VS static (inside, outside) 1.1.1.1 2.2.2.2 netmask 255.255.255.255

  2. when I'm setting up a router as a CA server and it is necessary to "export" the key, whatever my method of exporting the key?  If so, in which method call for which solution?

  EX: key export cryptographic rsa ciscox pem URL nvram: cisco VS. exporting key 3des cryptographic ciscox pem 3des rsa terminal cisco

  3. If I have to mark a packet with a DSCP of X value, matter if I use the 'set dscp' VS 'set ip dscp?  If so, what is the difference?

  FXY

  Policy-map X

  class X

  the dscp X value

  VS

  Policy-map X

  class X

  X ip dscp value

  I guess pertaining to 2, if i was speaking in terms of from a cisco router to another cisco router - would terminal be acceptable?
  
  

  Yes, the "Import cryptographic key" command can take a url and also from the terminal entrance. In this terminal case wil is much easier.

• Windows 7 starts questions about mac and office 2010 following an installation

  It's a long cut as short as vent. I've been miss sold a record of upgrade of windows 8 full disk-shaped, with norton and office 2010. My goal of creating windows on my mac for a course I'm taking. After that know I need windows 7, I bought it online. I created a partition of 80g on my mac charge windows 7, then norton. Until I loaded the office that I was invited to perform the update from apple in the windows software 7. Note before I installed norton, I load boot camp mac utilities according to the instructions. So, followed by all as should be. The prompt update from apple was quick time, iTunes and airport, I checked all and then updated. Then I loaded office 2010 and obtained throughout the process from the Microsoft site. On the last part of the installation, the installation failed due to a mistake of hanging iTunes. I tried again and again, I fixed the update to iTunes to add and remove the section of windows. Then, I got different errors. I decided to remove the whole score without uninstalling all programs again. When I get to the windows live, that this falls priming. I get various error messages whenever I try to start the process. As a header of Bank pool, fatal error and so on. Can anyone help? What is the damage?

  Hello

  Thanks for posting your query in Microsoft Community.
