• Why disable SuperFetch on ssd, if the RAM is much faster than the ssd?

  Directed by Microsoft that SuperFetch and PreFetch must be disabled, if the OS is installed on an ssd, in accordance with article http://support.microsoft.com/kb/2727880. But SuperFetch is used for loading the data components of applications, which were very often used for RAM. Although the ssd is faster that a hard drive is not faster than the RAM. So, I do not understand why Microsoft suggest disabling this feature. The only reason why I want to understand, it's because of a limited RAM. If the RAM is sufficient beyond 6 GB, if we disable SuperFetch, then the boot time and increase the loading time of most used applications. I miss something here?

  The other question is about PreFetch. I feel, maybe wrong, it does the same thing with SuperFetch, with one major difference. It loads all the information data on the ssd or hard drive, instead of the RAM, in order to accelerate the launch of applications and time when the OS is installed on a hard drive to boot. If I'm right, let's disable the PreFetch it stores information for one ssd or hdd, while SuperFetch stores data of RAM information, which is much faster and so it must be enabled if there is a sufficient RAM.

  I look forward to reading the notice of a Microsoft software engineer.

  Hi Leventis,

  Prefetch copies frequently accessed files together into a contiguous on the disk area so that they can be located and loaded more quickly. That it takes a lot of old drives to recover data faster.

  SuperFetch predict what applications you run next and preload all the necessary data in the memory. She has also done that with startup files. And for all the three days he sends a defragmentation command to the OS drive that will cause problems in the SSD drives.

  In traditional hard drives (HDD) data are scattered throughout the disk, so that the operating system for access, it will take more time. It is suggested to perform a disk defragmentation. But storage technology is different in SSD, where, it records the data dynamically and it recovers more quickly. Who will be low down the burden on the RAM and the RAM can be used for uses such as for the opening of the games graphics high-end, etc..

  Hope this information is useful.

• Clean install of Windows a lot faster than the preinstalled system?

  My satallite comes with windows 64-bit installed.
  Since a lot of people suggested, here and elsehwere, a clean installation making consierably faster than the pre-installed windows (all bloated and unwanted software uninstalled with the uninstall program).

  Although fresh installtion was faster without drivers and programs, it has become more or less the same after installation of all software, etc. (perhaps a difference of 2 to 4% in the use of RAM) (over 4 GB)

  Is this normal or do others go much faster on any new install, for me, this effort has proved there is not a lot of use to do a clean install to drive retail.

  Ideas, wiers and feed back?

  See you soon

  Many pre-installed utilities are required for correct functionality and it can be a headache get these functions to work after installing a street copy of Windows.

  You will find that when you install Antivirus software on a street copy of Windows, it will happen similar to the pre-installed Windows installation. So if you want that the installation of Windows pre-installed perform better, uninstall the Antivirus should do the trick.

• major differences of exadata database, listener, process than the normal RAC environment?

  I would ask for any input about the major differences of exadata database, listener, process than the normal RAC environment.

  I know now the exadata have not only SCAN listeners, but many other listeners. expert here can provide clarification?

  Thank you

  All the right questions... Welcome to the world of Exadata.

  These are questions that could get into a lot more detail and discussion than a forum post. At a high level, you certainly don't want delete all indexes on Exadata. However, you need to index and an indexing strategy will change on Exadata. After you move a database from one not Exadata Exadata environment you are probably more indexed. Indexes used for OLTP transactions real - looking one or a few lines among others will usually quickly with an index. The index used to avoid a percentage of records but always returning number of records can often be moved. On the index depends on the nature of the workload and your application. If you have a control on the index, then test your queries and DML with the index (s) invisible. Check your implementation plan, the columns io_cell_offload in v$ sql, smart scan wait events to ensure you get intelligent analysis... and see if the smart scan is faster than using the index (s). The real-time SQL Monitor is an excellent tool to help with this - use dbms_sqltune or grid/cloud control.

  Parallelism is a great tool to help still speed up queries and direct path loading operations and can help prompt smart scans... but use of parallelism really depends on your workload and must be controlled using DBRM and the parallel init parms, possibly using same parallel declaration put on hold, so it is not overwhelm your system and cause concurrency problems.

  If you have a mixed environment of workload or consolidates databases on Exadata so my opinion is IORM plans should certainly be implemented.

• Is faster than the HP Mini 110 Microsoft Surface?

  My HP Mini 110 series netbook is SLOW and it is 2 years old and the Microsoft Surface seems newer, but I want to know if the Microsoft Surface would go faster (for example, loading programs and files, etc.)

  The HP Mini 110 has an Intel Atom processor and the Microsoft Surface has an ARM processor.

  The Microsoft Surface would be faster than the HP Mini 110?

  It must be such that it is a newer CPU, but until the Surface is in the hands of consumers, we do not have really the real world benchmarks. I am 100% sure that whatever that is released by Microsoft or others would show much faster and better in all aspects. But these are marketing people making conversation, not technicians running the real numbers.

• Updated data are larger than the buffer cache

  Hi Experts,

  I have a small request. I have a table called CONTENT to have 12 GB of data. Here, I pulled a single update statement that updates to 8 GB of CONTENTS table of data using 1 GB of database buffer cache?

  How 1 GB of the Database Buffer Cache will be used to update the 8 GB of data? Level architectural any additional changes will happen (than usual) when executing "Updated data is larger than the buffer cache"?

  Could someone of you please response. Thank you

  Database: 10.2.0.5

  OS: Power 5-64 bit AIX system

  Hello

  the basic mechanism is the following:

  needed to update data blocks are read from the data files and cached in memory (buffer cache), the update is made to the buffer cache and the front of the (UNDO) image is stored in the segments of cancellation, operation (update here) is re-encoded to redo buffer until it goes again files If the buffer is samll or we need more space in the buffer cache, or we have a control point or... Oracle writes back the block modified data files to free the memory buffer for the more blocks.

  While the other runs the update of transactions can read before you change the image of CANCEL if validation, at the end of the transaction done change is confirmed and validation is recorded in the redo. If the cancellation is made at the end of the transaction before the image is "restored" and rollback is saved in do it again.

• Is faster than the local AIR IOS app remote SWF SWF because I can ' t use the unloading code.

  Are faster than the local SWF on AIR IOS app remote SWF because I can't use the code to unload on IOS of AIR.

  my local code:

  Stop();

  import flash.net.URLRequest;

  import flash.system.ApplicationDomain;

  import flash.system.LoaderContext;

  import flash.filesystem.File;

  import flash.filesystem.FileMode;

  import flash.filesystem.FileStream

  go_level_2.addEventListener (MouseEvent.Click, Level_2);

  function level_2(event:MouseEvent) {}

  var loader2:Loader = new Loader();

  var loaderContext2:LoaderContext = new LoaderContext (false, ApplicationDomain.currentDomain);

  var file2:File = File.applicationDirectory.resolvePath ("level2.swf");

  loader2. Load (new URLRequest (file2.url), loaderContext2);

  addChild (loader2);

  }

  Because it works for me, because I can't unload the SWF app file en becomes slow, I'll put the SWf file "s on a remote location.

  But I can't imagine what is happening when I loaded the SWF file remotely. It remains on the server, or it remains on my application when I unloaded it, and the app gets also larger. I hope you can help me because I went on the internet for a week and do not now how to go further.

  I had a similar problem, but not on iOS.

  Maybe my solution might work for you too, however.

  The problem was this line:

  new LoaderContext (false, ApplicationDomain.currentDomain);

  Do not reuse the same field of application, or you will never be able to get rid definitions and thus the SWF loaded.

  Instead, make a new child application domain for the current domain, keep track of it and it has as well as the rest of the SWF file when you are finished.

  Example:

  var loader2:Loader = new Loader();

  var appDomain2:ApplicationDomain = new ApplicationDomain (ApplicationDomain.currentDomain);

  var loaderContext2:LoaderContext = new LoaderContext (false, appDomain2);

  var file2:File = File.applicationDirectory.resolvePath ("level2.swf");

  loader2. Load (new URLRequest (file2.url), loaderContext2);

  addChild (loader2);

  Then

  function finishLevel2(event:Event):void

  {

  var loader2:Loader;

  	loader2 = Event.Target.Loader;
  	loader2.parent.removeChild (loader2);
  	loader2.unloadAndStop (); appDomain2 = null;

  }

  Note that the definitions of the classes of the loaded SWF file will be available in the new application domain.

• Shared pool larger than the buffer cache

  Hi all
  
  My database is 10.2.0.4 running linux platform
  
  No .of 2 cpu, RAM-2 GB
  
  SGA_TARGET wa set to 1 GB.
  
  Initially the memory have been configured as a shared pool around 300 MB and the buffer cache about 600 MB.
  
  When I questioned the v$ sga_resize_ops views I found some interesting results.
  
  Many operations and growth reduction were happened and the current size of the shared pool is about 600 MB and buffer cache is 300 MB. (this happened during last 1)
  
  I guess that the buffer cache must always be larger than the size compared to a shared pool. My assumption is right?
  
  Is it because of sql code using the do not bind variables resulting in growth shared pool? No relaods and radiation are almost ignored I think it should not be the case.
  
  Also no lock events listd in the top5
  
  I've also seen the 15% of the shared pool is marked as being of kGH:NO ACCESS, which means that the part is used for the cache buffers.
  
  Should I set the lower limit for the shared pool and the buffer cache or can I just ignore it.
  
  Thank you
  rajdhanvi

  You change your question now... your question was that he has sharedpool large size > buffer cache is acceptable... . Check your own second post... for your new question now is why pool continues to increase and partly used as buffer cache... the proof is given by tanel poder y what happens when EAMA is used... For the Kingston general hospital: NO ACCESS means that no one else could touch...

• R7000 Nighthawk Wired is faster than the wireless

  I currently use a Nighthawk R7000 and after the speed test internet using speedtest.net, I found that a desktop computer that is connected directly with ethernet is more than 100 Mbps faster than a wireless laptop which is the only room away from the router (wired office gets 140 ~-~ 160 Mbit/s, while the laptop is ~ 30-40 ~ Mbps).

• What can I do if the script runs faster than the network?

  I wrote a script between applications moving to InDesign, where he begins to AppleScript, to Photoshop, which AppleScript runs a JavaScript script to perform various tasks.

  It works beautifully on my laptop at home where I do my development. Yesterday, using me as a Guinea pig, I tried it in the office.

  On the third round, I was horrified to see the ExtendScript Toolkit pop up with an error message (about as welcome to see an AppleScript script, asking the user to open the Script Editor and fix a script).

  The error message was that app.bringToFront (); was not a valid function.

  This was the case in InDesign, which has a different activation function, and I realized that, even if my AppleScript called Photoshop activate, I was still in InDesign.

  The app.bringToFront JavaScript was so called because I had joined my code in the model of Tranberry.

  So I pressed the button stop on ExtendScript, returned to InDesign and represented the script. This time he worked as usual.

  Occasionally on our network we spend some time beachball - watch as a communication happens in the background. So I guess the time wherever the error was thrown was on one of these downturns in the network.

  The passage of InDesign, Photoshop is not happening pretty fast, but the script has run and has issued an order Photoshop JavaScript while I was still in InDesign.

  In AppleScript this unhappy communication with users can be avoided using blocks '... try error'.

  Is there an equivalent of the error handling in JavaScript that would allow me to avoid being tossed in the ExtendScript Toolkit and give them a friendly message to apologize, explaining what had happened and inviting them to try again?

  JavaScript has try/catch blocks

  try {}

  app.bringToFront ();

  } catch (e) {}

  error handling code

  }

  Or you might be able to use an if statement

  If (app == 'photoshop') {}

  app.bringToFront ();

  } else {}

  app handle not photoshop

  }

• In addition to making video is the most powerful 60 d or faster than the 50 d.

  I have a 50 d is there one reason other than the ability to make the video to purchase a 60 d.

  Canon made a large step backward with the 60 d, I agree with other posters.

  The articulated screen is nice for video, but really not so valuable to the shooting yet. In fact, I consider the rebel T5i to be upper-middle to the 60 d and which is reflected in the price of these two bodies ($700 for a 60 d) and $850 for a T5i.  Don't 'upgrade' to the 60 d.  The next update of the 60 d is now the 7 d, which is a fine camera.

  Canon seems to work in three directions: creation less expensive cameras full frame (6 d vs 5DIII), the upgrade of the rebels as well as a transfer line which was the 40 d, 50 d to the 7 d product line.  I think the 60 d will be the last body "double-digit".  In fact, the EOS - M has the same internals as the T5i but in a small body.

  For everyone (except the 60 d

• something faster than the UNION ALL?

  Hello
  
  I have two tables, with 20% and 80% of a total Group of data.
  The next time you press data, I need to have one top index so that the total dataset can be scanned.
  
  The result of this update is an update of the two tables.
  
  Here's my question (pls ignore syntax errors):
  
  I could do something like:
  
  create new_table
  As select * from t1
  UNION ALL
  Select * from t2
  
  change new_table add a primary key (acc_no)
  
  and then
  drop table t1
  drop table t2
  
  then the next cycle of treatment happens that, using new_table and a new set of entry, the t1 and t2 are filled (updates/inserts; and non-modifications/old)
  
  Then, new new_table is generated by t1 and t2... with a new index.
  
  This table is used again to read the next incoming batch of data, new filling t1 and t2...
  etc etc.
  
  actually, we have table t1 to send out of the database (flatfile). Then maybe we can do something faster as well. Maybe we don't need two tables at all?
  
  
  QUESTION 1:
  rather than generate a new table OF T2 T1 UNION ALL, I rather have the new table 'to be' the two tables? In this case, I just need to build the index on the table. Of course, t1 and t2 would disappear, but I have to drop them in any case for the next set of data.
  
  QUESTION 2:
  a little more advanced, is this table that combines all the results in the next 'as-is', must in fact be a table? I just need the appropriate fields (hm, in fact - all - fields) so I can make a new t1 and t2; There may be some smarter way to do it, without actually creating a new table t1 and t2 all the time...
  
  a big thank you in advance, your help is greatly appreciated

  Hi Dave Hemming.

  two thoughts on this approach,
  first of all I have not needed to keep the info on what were t1 and t2; they can be recessed. Rather the other way around, t1 + t2 will be "reborn" in the next run, based on the staging of new data and the "union all" table of the previous run (t1 + t2). then you see IS t1 + t2, after which t1/t2 would become useless.

  No, I do not say that you will not regenerate the tables t1 and t2. There is only one only true table new_table. Everything you would do the table t1 that you do view t1 and it is done as if by magic to the underlying new_table. Even with t2 - there is an opinion, not a table.

  The other approach is a view new_table which is a union of the tables t1 and t2, but then how do you index?

  The SSD used by Apple in a Mini 2012 is not necessarily the same brand and model from the one used in an iMac of 2015. Then there is a dual-core or quad-core i7 in the Mini. iMacs usually had the quad-core processors, I think.
