Windows 8.1 Hanging / performance issue
Hi ,
Today i clean install using windows 8.1 and after that i am facing lot of issues. like,.
1. Installation itself very slow. ( extracting files took almost 30 mins )
2. After successfully installed . ( by clicking any icons it hangs for 2-5 seconds ) then it responds.
3. whenever i typing in notepad or over internet explorer its letters are getting missed out due to hanging issue.
4. even i re downloaded the win8.1 pro iso , tried on different handrive, but still result is same ( handing ).
5. but i having issue only with this 8.1 where i am already using windows 8 pro without any issue on my pc
6. configuration of my pc ( Core to Quad processor ) with 4.5 TB hardrive.
Need suggestion how do i fix this issue.

To find what is causing your computer to use more CPU than it normally does you need to run this.
Install the WPT (windows Performance Toolkit) http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt.aspx ,
Open a CMD prompt with administrative rights (right click it>run as admin) and run this command for 60 secs to capture the high cpu usage:
xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d cpuusage.etl
The trace will run and give you a warning then revert to a C:\ prompt
The log will be in C:\windows\system32.
It should be called cpuusage.etl
Please zip the file and upload it to skydrive (or another file sharing service) and put a link to it in your next post.

Windows 7 Enterprise login performance issue RODC site
Hi,
We are deploying windows 7 enterprise to all our computers in our domain and we didn't have any performance issue on any site with Full DC. Now we are facing a problem with our multiple sites with RODC but only with new deployed windows 7 (WinXp is not having
this slow login problem). The problem is very strange. Whatever a user start a session on a desktop or laptop with Windows 7, wireless or cabled, when the user enter his credential and press the "validation arrow" next to the password nothing happen
(well it look like nothing happen). After 5 to 10 minutes at this logon screen, we finally see the logon process start applying domain policy, preparing the desktop etc etc and this take less then 10 seconds but remember, we just wait 5 to 10 minutes until
the computer process the "process my log in" botton. Sometime, the CTRL+ALT+DEL screen come back and when we press them we got nothing, we have to wait for the "logon" to occur before doing anything else with the computer.
I've looked to many way to solve this but for now nothing worked.Hi,
Sorry for my dilatory reply. How about using a same user account to log on XP computer? Will it logon fast?
Have you tried to add a user account into Allowed RODC Password Replication Group for test? This problem probably caused by the password authentication problem In RODC host.
For further investigation, you can try to use Network Manitor at RODC host to capture package of client machine authenticate to a domain controller.
The blog about Understanding "Read Only Domain Controller" authentication
may be helpful.
After the above steps, We can narrow the cause of this problem.
If problem persists, this problem may caused by Windows 7 Client performance. Generally speaking, the problem like this most probably caused by sercurity application problem. You can try to disable or uninstall security application temportaily for test.
If there is any progress, please feel free let us know.

ITunes 7.3.2.6 and Windows Vista Performance Issues
I recently purchased an 80GB iPod, and downloaded iTunes promptly, disregarding all the negative attention about how "iTunes crashes your computer" or "iTunes kills Windows". So far, the only real problem I've had with iTunes is the amazingly poor performance it has on my computer. When iTunes is minimized to the system tray, or compressed into Mini Player mode, it runs better, but not well.
Running in the full mode, the player bogs down my computer substantially. Knowing my laptop isn't a powerhouse, I expected a slight bit of slowdown, since there is some evident with QuickTime.
UPDATE: I've just stumbled across something. Apparently, wiggling my mouse over the iTunes program, iTunes runs about two or three times faster. The moment I stop moving the mouse cursor over the window, the speeds return to slow. It seems to only do this during the "Processing Album Artwork" phase. Bizarre? Very. Any explanations?
I find this to be very annoying, especially when syncing. Syncing my library (which is about five or six gigabytes) takes an amazingly long time. Are there any workarounds, registry hacks, or anything else that can be done? Thanks!

ITunes on Windows 7 performance issues - slow and hangs
Is there any way to improve performance of iTunes running on Windows 7?
It has always been slow with lots of application hangs and stalls that will resolve themselves if you wait for iTunes to catch up, but I find it incredibly frustrating.
For example, when iTunes starts and if it is checking podcasts, the entire application is unresponsive until it finishes checking and refreshing podcasts.
Alternately, when viewing my iPad Air and looking at the list of apps installed via iTunes it can take 30 seconds before iTunes responds.
Considering that this is running on a system with a quad-core Haswell processor at 3.2Ghz, 16GB of RAM and Windows 7 x64 it is pretty unacceptable.
The efficiency at which iTunes operates is just appalling. I can run Adobe Photoshop and many more memory hungry and processor intensive applications than iTunes and get better performance than what I see in iTunes.
This is not specific to my system either. All of my family members have iPhones and their own computers and this performance issue exists on every computer I have ever run iTunes on.
Is there any way to manually tune performance because this is pretty crappy. It's been bugging me for years, but today just kind of feels like the last straw.I guess the answer is, "It's terribad, live with it"

Brand new with performance issues -- programs not responding, system hanging
Just this morning I began migrating from a Dell Inspiron 1525 laptop that has been generally reliable for the better part of 3 years (monitor housing is literally falling apart but still works great... check E-Bay later for spare parts! lol)... migrating to a Toshiba Satellite C655D-S5136 laptop running Windows 7 64-bit. It's literally right out of the box 5 hours ago and I've been reinstalling programs, transferring files, etc.
The problem is that I'm already noticing a lot of performance issues. The system (and/or programs) seem to get caught often... resulting in frequent "Program not responding" messages (some of which the system manages to bypass)... and a few of the "This program closed unexpectedly" or "This program stopping responding... do you want to check online for a solution or just close the program?" messages.
This is happening on multiple programs... tax prep software TaxAct update dialog hangs after 256 bytes downloaded every time, AVG Anti-Virus was hanging although never gave me a not responding message, Internet Explorer has stopped responding a couple times, Windows Live Mail did often, especially when I was using IMAP (since changed to POP3 and problem seems to have resolved but still). Even opening the start menu a few seconds after plugging in an external hard drive lagged the system like hell for a full two minutes until it caught up with itself.
This is unacceptable in a brand new machine. I was getting a few errors like this on my Dell every now and then but I chalked it up to an old machine that had never been wiped and had a failing hard disk. I understand the computer moving slower, especially as I've been installing a lot, running antivirus, downloading all at once, but no way programs should simply stop responding this often. I could do twice the activity on my Dell and have no issues.
I've uninstalled several of the preloaded programs... the antivirus, quickbooks, etc. I've also disabled and/or uninstalled several of the other programs like Toshiba Reeltime and Toshiba Zoom Manager or whatever that was. Nothing has seemed to help. And that's not surprising... the speed is great, it's that programs are getting caught so often, sometimes every time or every other time I open up a program.
Is this a Windows 7 thing? (This is first time using Windows 7, coming from Vista). Is it a Satellite thing?
Anyone have any suggestions? Is it possible there's just some component that's bad? Processor, RAM, etc.?
Thanks... very frustrated!I may have found a solution. I changed my startup programs and stopped some of the Toshiba software from running at startup. The ones I stopped are listed below. I have used the laptop heavily for two days now and have not had any problems. It actually runs very fast. I hope this will help.

On googling this seems to be an issue with java file handling on windows servers and I couldn't find a solution yet. Any recommendation or pointer is appreciatedHi shubhu,
I just analyzed your partial Thread Dump data, the problem is that the ajax4jsf framework ResponseWriterContentHandler triggers internally a new instance of the DocumentBuilderFactory; every time; triggering heavy IO contention because of Class loader / JAR file search operations.
Too many of these IO operations under heavy load will create excessive contention and severe performance degradation; regardless of the OS you are running your JVM on.
Please review the link below and see if this is related to your problem.. This is a known issue in JBOSS JIRA when using RichFaces / ajaxJSF.

Performance Issue in NetworkInterface.getNetworkInterface in windows JRE 7
NetworkInterface.getNetworkInterface() call takes 10 times more time when run in Windows JRE 7. The same call runs much faster in JRE 6.
Sample Program,
I wrote a small program which just fetches the network interfaces using java.net.NetworkInterface.getNetworkInterfaces() as below,
------------------------------------ Program Start ------------------------------------
import java.net.*;
import java.util.*;
public class PerfNetTest {
public static void main(String args[]) throws Exception {
long startTime = System.currentTimeMillis();
Enumeration niEnum = NetworkInterface.getNetworkInterfaces();
long endTime = System.currentTimeMillis();
System.out.println ( "Total Time Taken For One Call: " + (endTime-startTime));
startTime = System.currentTimeMillis();
for (int i = 0; i < 10; i++) {
niEnum = NetworkInterface.getNetworkInterfaces();
endTime = System.currentTimeMillis();
System.out.println ( "Total Time Taken For Ten Call: " + (endTime-startTime));
------------------------------------ Program End ------------------------------------
Compiled the above code in Java 6 and ran the above program in JRE 6 and JRE 7. JRE 7 takes approximately 10 times more time than JRE 6. This leads to a huge performance issue in our project.
I ran it 5 times in each JRE versions and below are the test results,
When run in JRE 6
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 18
Total Time Taken For Ten Call: 81
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 17
Total Time Taken For Ten Call: 80

Total Time Taken For One Call: 18
Total Time Taken For Ten Call: 79
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 18
Total Time Taken For Ten Call: 80
When run in JRE 7
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 98
Total Time Taken For Ten Call: 891
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 100
Total Time Taken For Ten Call: 869
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 98
Total Time Taken For Ten Call: 859
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 99
Total Time Taken For Ten Call: 871
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 99
Total Time Taken For Ten Call: 888
Is there any other way to optimize the performance in JRE 7 internally, Can the above issue considered as a bug with Windows JRE 7? Can I go and submit a bug for this?I have simplified the program to point out the exact issue. In the actual usage we need to know immediately or whenever there is an ip change, it might be because of the change in ip to same nic card or when connected to a network via any of the nic card (wifi enabled, etc).
Overall it is particularly important to as we used to get the NetworkInterfaces for every features. As a result of this, 60 feature which gets executed roughly around .5 milliseconds in java6, now consumes almost 6-10 seconds in java 7.
Also in our client server application, where client queries for NetworkInterfaces and further sends a requests to the server where we have to support at least 100 transaction per seconds(TPS for complete client-server throughput), with 100's of client systems querying for its own NetworkInterface is consuming time and certainly reduces the overall throughput.
Currently I am more inclined to cache it and refresh in a separate thread internally, but certainly I wanted to avoid it because the throughput will be less for the first request and especially when it works perfectly fine with java6.

Multiple severe performance issues under Windows
I own a Macbook Pro, and have used it happily for around a year. However, the hard drive was too small (no idea why I decided to go for the 80), and my music library kept growing. At the same time, I needed a Windows machine for various other purposes, so I bought a Dell with Vista. I successfully transferred all of my music over to it, and downloaded iTunes. It installed fine, and all of my music showed up, and plays.
Here are the problems. Compared to OS X, iTunes on Windows *****. Unbelievably. It's incredibly sluggish (even basic things like scrolling through your library - smooth as silk on the Mac, but choppy on Windows. Resizing the window doesn't work well, either), and it has to have at least a few major memory leaks.
I'll give you some specifics.
Acting "Sluggish"
- Scrolling through my library (with either the scroll wheel of the mouse or the scrollbar on the right) is very choppy. This is not the case with any other application on my computer - scrolling through a list of entries is smooth and works well.
- Resizing the window frequently doesn't work. I'll grab the corner, and move the mouse over to another area. The mouse will be on a different part of the screen, but the iTunes window will not have resized at all. If I move the mouse, the window then resizes to where the mouse last was. In other words, if I want to resize the window, I have to grab the corner, drag to another size that I think I want, and then move the mouse a little to get it to go. This animation is also very choppy.
- Coverflow is very slow and moves at a very low framerate, fullscreen or otherwise.
- Oftentimes, the first keystroke (or two) will be completely ignored. So, for example, I'll hit Ctrl+L to get to the currently playing song, and have to press it 2 or 3 times in order for it to have any effect.
Memory Issues
- When I start iTunes (in the smallest window possible), it takes around 56 MB of memory, not playing anything. Once I start to play a song, it jumps a little, but ultimately doesn't change that much (now it's at 60 MB instead). I resized the window to be on most of the screen, and it's now at 66. Scrolling through my library on List View, while slow and choppy, doesn't take up any significant amount of memory. However, as soon as I change to either the "grouped with artwork" option or coverflow, bad things start happening.
- Grouped with Artwork: At the beginning, iTunes is taking up 70 MB of memory. Every time I hit Page Down, another 3-4 MB of memory is added. This memory is never released. So now, having scrolled down from the top a little, iTunes is now sitting at twice what it was at the beginning, or 145 MB. It's now taking up more memory than Firefox.
- Coverflow: Starting out at 145 MB from the earlier view, switching to coverflow immediately makes the memory jump to 170 MB. When I scroll through the albums, the memory then jumps anywhere from 40 - 50 MB. After a bit of clicking, iTunes is now taking up 1,106 MB of memory.
I minimize iTunes, and 1 MB of memory is freed. iTunes is now at 1,105 MB.
Moving out of CoverFlow view does a good job at cutting some memory use, but it's still at 540 MB. And at this point, I'm back to where I started (in terms of what iTune's doing: list mode, small window, not playing), only at 9 times the memory use. As far as I know, there's no way to reclaim that memory.
Various Issues
- iTunes will frequently disregard the first or even second keystroke, as mentioned above.
- This scenario is a little harder to describe, but I'll do my best. iTunes is the foremost application. The focus is on song panel (the main part), so that pressing the Up and Down arrow keys cause the "currently selected" blue background thing behind a song to move up or down, enter plays the currently selected song, etc. I Alt-Tab to another application, and then Alt-Tab back. It looks like I'm in the same situation as before (the currently selected song is blue, instead of grey), but the up and down keystrokes do nothing. I'm apparently in a different section of iTunes. Pressing Tab brings me to the left panel of iTunes - the Music / Movies / Podcasts / Ringtones / etc. part, but the up and down keys don't do anything there either. Tabbing again takes me to the search field, and that works. And tabbing once more brings me back to where I should have been as soon as I Alt-Tabbed back to iTunes.
- A variant situation: focus is as described at the beginning, and I Alt-Tab out and back into iTunes. Again, the up and down keys don't work, but then if I press Shift + Tab (to go to the previous field), it starts working again.
This issue is much more of a pain than it sounds. If I'm in iTunes, and I'm chatting online, for example, I might need to switch out quickly to type a line in, and then switch back, but the workflow has been completely disrupted because I can't navigate with the keyboard anymore.
- When editing a song title in iTunes, I select it first, and then press F2. This causes the title to become a "rename" field, which works mostly fine. With one exception. Generally, in these fields, you edit the title to your heart's desire, and then press Enter to signify that you are done. However, in iTunes, if I have a song title "blowin' in the wind", and I want to capitalize it, I'll hit F2, and then move the cursor over to the beginning of the title (in other words, to right before the "b"). My goal is to delete the lowercase b, and replace it with an uppercase B. So I press Delete, and then type B. However, as soon as I press the Delete key, iTunes deletes the character, and then closes the rename field. It's as though I pressed Delete and then Enter. If I then type B, I'm taken the first song starting with a B, which is not what I want at all.
- iTunes doesn't work with Vista's window preview (Aero interface, Alt+Tab or hovering over the program in the tray at the bottom) when it's minimized.
- When I have iTunes on in the background, and plug in an iPod, it all works fine, except for when I bring the window up. For whatever reason, iTunes doesn't repaint the window right at all. It's a horrific mixture of whatever songs were in the list view before and the iPod options.
I'm sure I have more issues, but those are the ones that come to the top of my head. Note that I have none of these problems in iTunes on the Mac.

Windows is the lowest performing host for GroupWise, so that is a part

How are you monitoring memory usage? I've found that the vCenter tools
aren't a good indicator of that, where as the Windows tools are better
in that respect. The biggy is that you don't want much paging to disk.
How much do you have assigned to this VM?, how many cores? And are
these ESX box(es) over committed on those two?
Those settings on their own don't really mean a whole lot. What we need
to see is what is actually being used, and if you are running out of
them, then upping those specific numbers can help. The best way is to
watch the POA web interface for the relevant settings.

POA performance issues under windows 2008 R2
Hello - we are running GW 8.02 hp3 and recently moved our main post office (~600 users) from Netware to Windows 2008 R2 (running under Vsphere 4.1).
We have started seeing intermittent slow performance issues esp. when moving a message from one folder to another, or sending a broadcast email.
It doesn't appear to be a hardware resource issue: disk queues don't exceed 1, with low latency (7-15ms) and we're not cpu or memory bound (that I can see).
Here are our current config settings:
Message Worker Threads: 15
Maximum GWCheck Worker Threads: 8
C/S Handler Threads: 30
Max Physical: 2048
Max App Connections: 4084
Soap Threads: 20
We don't see any serious errors in the logs when performance becomes slow. Could this just be a tuning issue?In article <[email protected]>, Javerkio wrote:

Sun ONE 6.1 Performance Issues - Sleeping / Hanging
We have been running the Sun family of web servers for many years now, and ran Netscape Enterprise Server 3.6 for a long time.
Several months ago we upgraded to Sun ONE Web Server 6.0 and then 6.1. We have not had any issues until the past few weeks.
Specifically, the web server appears to 'go to sleep' or 'hang' for many seconds - sometimes up to 45 seconds - before processing any requests.
The server will accept the connection immediately but will not return a page. If left alone, the problem will go away, only to return again. A stop and start will also cure the problem.
Some background: 6 web servers run on this same server (Sun E250 2x400 MHz, 1280 MB RAM) - these servers are all relatively lightly loaded. Copper gigabit connection for network.
Primary data is static, with very few cgi-bin scripts and no applets or server-side Java.
All 6 servers have DNS lookups enabled with caching. The server also has a local DNS caching server running (BIND 9) which is used to help performance.
One of the 'public' web servers (external people can access it) is the one showing these performance issues. I've enabled statistics, and it seems during these 'sleepy' periods I see the following in /.perf (which it finally returns): (I am fetching /.perf every minute and timing how long it takes to fetch it, then saving it in a separate file):

Why do I have all of these processes queued on the server?
Is DNS causing this? I know Sun ONE 6.x does NOT have asynchronous DNS implemented (although it is an option, it has no effect). Did Netscape Enterprise Server 3.6 has ASync DNS implemented?
We would like to avoid turning off DNS resolution for a number of reasons. However, what really bothers us is that this web server's performance suddenly became a problem while the other 5 servers see FANTASTIC performance and never go to sleep (although some of them are NOT accessible from the general Internet).
Has anyone else seen this?
As a side note, all of these web servers are using a NSAPI plugin that I wrote years ago. It's purpose is access control and automatic forwarding to different pages. It also uses DNS hostnames, but thinking it might be a problem with this web server, I've disabled DNS on the plug-in. It has not helped. Again, this plug-in has worked great for years and is quite straightforward and simple.
Something tells me there is more going on here - thoughts or ideas?
We're getting immensely frustrated here.
In desperation we've made some magnus.conf changes but to no real effect (partially listed below):
DNS on

StackSize 131072
CGIWaitPid on
AsyncDNS off
KeepAliveThreads 2

Thanks for any pointers,

Service Manager 2012 SP1 consoles hanging or slow performance issue in Virtual Environment
Hii,
We are facing SCSM SP1 console performance issue which is utilizing high CPU and working deadly.
For information, our SCSM is in Virtual environment via Hyper-V.
When running the console over an RDP session to a Hyper-V virtual machine, we have to be careful not to maximize the console so that it will remain fast. If we maximize on the VM, the console is so slow as for it to be unusable.
Can someone share his experience, please?
Regards, Syed Fahad AliHi Sayed,
This is a bug and hopefully Microsoft team will solve it soon. if you can to vote for this bug here

Performance Issues with Photoshop CS6 64-Bit
Hello -
Issue at hand: over the course of the last few weeks, I have noticed significant issues with performance since the last update to PS CS6 via the Adobe Application Manager, ranging from unexpected shut downs to bringing my workstation to a crawl (literally, my cursor seems to crawl across my displays). I'm curious as to if anyone else is experiencing these issues, or if there is a solution I have not yet tried. Here is a list of actions that result in these performance issues - there are likely more that I have either not experienced due to my frustration, or have not documented as occuring multiple times:
Opening files - results in hanging process, takes 3-10 seconds to resolve
Pasting from clipboard - results in hanging process, takes 3-10 seconds to resolve
Saving files - takes 3-10 seconds to open the dialog, another 3-10 seconds to return to normal window (saving a compressed PNG)
Eyedropper tool - will either crash Photoshop to desktop, or take 5-15 seconds to load
Attempting to navigate any menu - will either crash Photoshop to desktop, or take 5-15 seconds to load
Attempts I've taken to resolve this matter, which have failed:
Uninstalled all fonts that I have added since the last update (this was a pain in the ***, thank you Windows explorer for being glitchy)
Uninstall application and reinstall application
Use 32-bit edition
Changing process priority to Above Normal
Confirm process affinity to all available CPU cores
Change configuration of Photoshop performance options

Performance issue in DB need help with analysing this ADDM report
Hi,
My environment:
Os: RHEL5U3 / 11.1.0.7 64 bit / R12.1.1 64 bit
Issue:
Few days are am facing serious of performance problem in our Production instance. Normally the issue will occur 5 to 10 minutes occasionally per day. At the time of issue we not able to access the EBS application its taking time to load. But backend all the oracle, listener and apps services are up and running. No locks at table and session level. Cpu and memory usage is normal.
We have monitored using "Enterprise Manager" for this issue and we found the wait session present more in Active session tab. At this time EBS application is not able access its loading too time. After some time the in Active session tab the wait session came normal and when we try to access the EBS application its working fine.
We try to find the cause of the issue by running addm report. But am not able to understand what its says. Kindly suggests me

Performance issue with Jdeveloper
Hi Guys,
I am experiencing strange performance issue with Jdeveloper 10.1.3.3.0.4157. There are many other threads regarding the performance issue in this forum, but the problem I have is a little bit different.
I have two computers: one is Athlon 3200+ with Vista and another one is P4 dual core 6400 with XP (service pack 2). Both of them have 2GB memory.
I am running the same simple project on both computer, but only the one with Vista has the problem. The problem is very similar to the problem mentioned in the thread:
Re: IDE has become extremely slow?
But it's much worse. It only happens only on JSF pages. Basically, any operations on the JSF pages are very slow. Loading the page, changing the attributes of a button in source editor, or even clicking the items in the design view take forever to run.
The first weird thing is that it may use 100% CPU, but it never recover, which means the 100% CPU usage never stops or when it stops, the Jdeveloper stops responding.
The second weird thing is that the project is not big. Actually, it's very small. The problem started to happen since last week. There are not big changes during the period. The only thing I can say is that we created two more JSF pages.
The third weird thing is that the same project never happened on the P4+XP box. When I open the project on the P4+XP box, it’s always fast and no CPU spike.
Any advises are welcome!
Thanks,
StevenHi Guys,
I re-made a simple test project for this problem and now I now always reproduce the problem in JDeveloper on both system (XP & Vista). Everytime I open this jspx file in the source editor and try to scroll up/down the source file, or manually delete an attribute, JDeveloepr will hang and the CPU usage is 0%.
