• WRT54GS - wireless performance problem

  Dear someone

  I am currently having performance problems with my WRT54GSv1.1

  Just received my new internet connection to 30Mbit. Unfortunately, I am not able to download at that speed. If I connect via one of the linksys router's ethernet ports, I'm a happy person, but using the wireless makes me a little less happy.

  Wireless: 15Mbit/s

  Through the cable: 27Mbit/s

  Network information:

  The distance between the router and the computer laptop 3-4 meters

  Linksys WRT54GSv1.1 - Firmware Version: v4.71.4

  Network wireless - g only mode

  TV - 6 (because all the surrounding neighbor use 10-11, I noticed using Cain Abel & wireless discovered 4.9.29)

  Security: WPA2-Personal (TKIP + AES)

  All other settings are default (just reset to the factory settings).

  Laptop:

  Windows Vista Business SP1 32-bit

  Intel PRO/Wireless 3945ABG (installed the latest drivers from the website of intel, default settings)

  When you check the diagnostic of Intel tools, it tells me the link is 54 megabits and pushes meter packages of 54 megabits, while all lower speeds remain the same.

  More diagnostic information:

  Percent missed beacons: 0

  Percent transmit errors: 18

  Current Tx power: ~ 32 mW (100%)

  Supported power levels: 1.0 mW - 32.0 mW.

  Hope someone can help me here.

  Thanks in advance!

  Kind regards

  Although wireless g "connects" to 54 Mbit/s, the maximum possible wireless "data rate" (in ideal laboratory conditions) is only about 20 to 25 Mbit/s.  Unfortunately, the phrase "in ideal laboratory conditions" generally excludes home intrusion!

  The aerial transmission for wireless connections is higher than for wired connections.   Thus, most individuals find that their Wi - Fi connection works at 50% to 70% of their speed of wired (LAN).  Your wired LAN being 27 Mbps connection speed, your 15 Mbps wireless speed is within normal limits.

  You might be able to tweak a bit more speed from your wireless network by optimizing all your wireless settings.  Here are a few suggestions:

  I guess you want actually to WPA2 encryption.  If so, set to AES only.   When you set the router to TKIP and AES, you actually tell the router to accept a WPA or WPA2 connection.

  Also, give your network a unique SSID. Do not use "linksys". If you use "linksys", you can try to connect the router to your neighbor. Also set 'SSID Broadcast' to 'active '. This will help your computer to find and lock on the signal from your router.

  Bad wireless connections are often caused by interference from other 2.4 GHz devices. This includes cordless phones, baby monitor wireless, microwave ovens, wireless mice and keyboards, wireless speakers and wireless network from your neighbor. In rare cases, Bluetooth devices can interfere. Even some 5 + GHz phones also use the 2.4 Ghz band. disconnect these devices and see if that solves your problem.

  In your router, try another channel. There are 11 channels in the band of 2.4 GHz channel 1, 6 or 11 generally works better. Discover your neighbors and see what channel they use. Because the channels overlap, try to stay at least + 5 or - 5 channels of your more powerful neighbors. For example, if you have a powerful neighbour on channel 9, try any channel 1 to 4.

  Also, try putting the router about 4 to 6 feet above the ground in an open area. Do not place behind your screen or other computer equipment or speakers. The antenna must be vertical.

  In addition, in the computer, go to your wireless software and go to 'Favorite networks' (sometimes called 'Profiles'). There are probably a few listed networks. Remove any network called "linksys". Also remove any network that you don't recognize or that you no longer use. If your current network is not listed, enter its information (SSID, encryption (if any) and key (if any)). Select your current network and make your network by default, then set it to auto login. You may need to go to 'settings' to do this, or you may need to right click on your network and select 'Properties' or 'settings '.

  If you continue to have problems, try the following:

  For wireless g routers, try setting the "baud rate" at 54 Mbps.

  If you still have problems, download and install the latest firmware for your router. After an update of the firmware, you must reset the default router, and then configure the router again from scratch. If you have saved a router configuration file, DO NOT use it.

  I hope this helps.

• Oracle 9i Java component performance problems

  Hello

  I am reorganizing a java component inherited because of performance problems.

  
  A java stored procedure is used to trigger a shell script that runs a java component. The component connects to a series of remote directories via ftp, gets the files and load them using slq * charger.

  Is there a better way to do this? I saw a few articles talking using a FTP interface directly from PL - SQL jump the java component entirely. It would be preferable to the current solution its?

• ViewObject range Paging performance problem

  Hi all

  I am facing a performance problem with the implementation of an obligation to programmatically add a number of extra where the parameters of the clause (using bind) variable in combination with range paging.

  My code looks like this

  ...
  
  ApplicationModule am = Configuration.createRootApplicationModule("services.DossierAM", "DossierAMLocal");
  ViewObject vo = am.findViewObject("DossierListView");
  
  // apply programmatic view criteria
  ViewCriteria vc = vo.createViewCriteria();
  ViewCriteriaRow vcr = vc.createViewCriteriaRow();
  vcr.setAttribute("Reference", "15/%");
  vc.addElement(vcr);
  vo.applyViewCriteria(vc, true);
  
  
  // enable range paging
  vo.setAccessMode(RowSet.RANGE_PAGING);
  vo.setIterMode(RowIterator.ITER_MODE_LAST_PAGE_PARTIAL);
  vo.setRangeSize(50);
  vo.scrollToRangePage(5); // Cause a java.sql.SQLException: Parameter IN or OUT missing for index.....debugging learned that the :vc_temp_1 bind variable is not filled
  // vo.scrollToRange(250); // Cause a java.sql.SQLException: Parameter IN or OUT missing for index.....debugging learned that the :vc_temp_1 bind variable is not filled
  
  ... 
    ...
  

  I found 2 solutions, but they both require an application of additional database that is, performance wise, is not acceptable.

  The first solution is to slip into an additional call to exectueQuery() before the call to function scrollToRangePage (int) or scrollToRange (int).

  The second solution is to use the method (int) setRangeStart instead of variants scrollToRange (Page). This method performs also 2 database calls.

  My question to you:

  Is there another way to satisfy the requirement of programming add a certain number of parameters of the additional where clause (using the variable binding) in combination with the pagination of the range without the need to perform queries of database 2?

  The code is tested with JDeveloper, 11.1.2.4.0, and 12.1.3.0.0 and behaves the same on both versions.

  Kind regards

  Steven.

  Have you tried to create truly VC with bind variable (rather than use binding implied var created by frame)?

• Performance problems since the update of 2015.6

  Hello together,

  Since I updated lightroom yesterday to version 2015.6 the performance on my machine is incredible bad.

  My system:

  -MacBook Pro (retina, mid-2012)

  -2.3 GHz Intel Core i7

  -16 GB 1600 MHz DDR3

  -NVIDIA GeForce GT 650M 1024Mo

  -OS X El Capitan (10.11.5)

  Lightroom synchronizes actually 1400 photos, but even if I stop this process, LR uses CPU so I can't work in other programs like Photoshop (updated yesterday, too). I detected this performance problem as PS freezes when I used the Healing Brush tool.

  

  I don't know what's happening LR, but is not ideal for my workflow.

  Does anyone have an idea?

  If I close LR I can work in PS, even though the Healing Brush tool is slower than in the version before. But I can't always close and open LR.

  Thank you

  regards Denis

  There are already dozens of threads discussing the same question in this forum as well as in the official comments forum here: https://feedback.photoshop.com/photoshop_family/categories/photoshop_family_photoshop_ligh troom

  You can restore 6.5.1 if you wish. Here's how: How do I roll back to Lightroom 2015.1.1 or Lightroom 6.1.1? Lightroom Queen

• HP Pavilion 15-n005sg: performance problems and worsens

  Hello

  I bought this PC here is a year, has been a very good PC with good performance, but has been doing more and more slow to the month, for example, I used to run Diablo 3 on average - high specification with 60 fps constant with no performance problems, but that in the end, I can't still running at ultra low care without screen freezes and fps drops to 1-2 as well as the League of legends and other games.

  It takes more and more time for my pc to turn on, which was like 30 ~ 40 seconds not takes like 3 minutes.

  the performance gets really bad and should not happen on a pc of 1 year.

  What can I do?

  An update of the system may be your best course of action.

  Your data, files, etc. will be retained. Any Windows apps store is kept.

  Any program that came pre-installed is preserved.

  BUT all programs which are not in the above categories will have to be resettled; your games, printer, etc.

• [ORACLE 10.2.0.5] performance problem with high enq: TX - line lock contention waiting

  Hello

  I have a performance problem involving high line response to locking conflicts that I can't wait.

  The application updates the specific table about 1200 times for my AWR report representing 2 hours.

  This update represents 98% of the db_time and wait to enq: TX - line lock conflict is:

  -83 796 waiting

  -245 441 seconds

  The application updates a row both an unprecedented SELECT UPDATES. This is the query:

• took vcap5-dca exam today and had laboratory performance problems

  Most of the time, the review ran ok. I was very impressed by the performance of the lab environment. I can say that I had to skip two questions I knew because the keyboard and mouse of entry would not work. After spending 5 minutes trying to get my keyboard and mouse works on one of the questions, I had to jump even if I knew the answer. It is unfortunate that, for a review of 400 dollar, you have performance problems that limit your ability to perform the review. Overall, I think I did pretty well. I was able to get about 19 questions answered to jump through the other 7 due to the performance and time. I acknowledge that the pace I started to was a bit slow, but laboratory performance degrade my ability to perform my best on this review. I would recommend to anyone who takes this review to make sure that you use a good test center. I drove 60 miles to my test center to make sure that I went to a good and always fell on issues. I could only imagine what it would have been like if I went to one of these centers of samples of groceries with a metropolitan WAN connection for internet :-) Now wait to see if I've spent 15 days.

  Has anyone else had this kind of questions? If so, where did you register a complaint?

  Hello

  The delay is a common thing for everyone outside the USA. She varies the amount of delay but it has been around since the VCAP-DCA 4. In regard to complaints they should normally be done the day of the test to the exam administrator otherwise pearson cannot do much.

  Good luck for the result!

• Isolate storage performance problems

  I'm looking for the most effective strategy to isolate a possible performance problem and to determine if storage is the cause.  VMware said that this physical device read latency and physical device write latency must be sheer 20ms lower and 10 ms on average.  I see peripheral physics average 11 percent read latency and write the average latency on some HBAs.  I see 120ms peak read latency and 240ms latency of writing on some HBAs.

  Suppose I want to isolate this issue - how to efficiently determine if these measures indicate the storage as the cause of the poor performance of the application?  (For example, storage VMotion virtual machine which is own LUN with no other VM and see if there is a difference in performance - something that does not require a lot of time).

  Migrate the virtual computer on a local storage on one of your hosts to see if latency goes away. Then you know almost for some it's a problem on the ESX Server or on the fabric. My bet is that it is on the fabric. Run perfstats on table and you will most likely find that you are maxing out the SECOND battery on the diskgroup to support for the LUN that you write to.
