Solaris 9 High Disk Usage
Hi,
I have an unusual problem with Solaris 9 servers I am responsible for. Occasionally a server will suffer from very poor performance, characterized by disk throughput ramping up to 100%. I figured there must be a process responsible for hogging the disk, so I first tried shutting down as many processes as I could. The problem is that the servers are distributed around the world, and I need to be careful not to stop so many processes that the server becomes unavailable. This did not yield a solution, so I found some tools to list disk usage by process. I found that when the disk usage is at 100%, there was very little process disk activity, so it was not possible to identify a guilty process. Strangely, one of the partitions affected (according to iostat) is the backup partition. The only solution I have found so far is to do a reboot.
Has anyone seen this problem before?
Thanks
Nick
Issue fixed. Kernel memory consumption caused by too much outgoing TCP connection. See http://forum.sun.com/thread.jspa?threadID=26311&tstart=0

High disk usage/high memory usage.
i keep getting high memory usage and high disk usage in ps cs6.
its slow when i open a file. how can i solve this problem.
thank you.
philip.Not to put too fine a point on it, but more than what? More RAM is almost always better, but you haven't answered most of the questions posed here. The answer might be different if you have 2 GB of RAM or 32 GB of RAM already. A 9 megapixel document could get rather large with a lot of layers, but again you've neglected to give any hard info about its size.
Regarding your video card, that's a bit of a judgment call you need to make. For Photoshop CS6 I currently advise people to try to get a video card that gets a score of 1000 or better on this benchmark: http://www.videocardbenchmark.net/high_end_gpus.html
Video card speed will matter when you're editing those 3D components and video card VRAM will also matter, but possibly even more importantly your GeForce 320 is a bit old, and nVidia may just not be doing their best driver work for it any more.
Everything in general will run more smoothly with a powerful modern video card. I like to recommend a VisionTek ATI Radeon HD 7750 - or if the computer power supply and your budget allow, the even more powerful 7850. VisionTek does a very good job with their hardware, IMO, and it comes with a lifetime guarantee.
Keep in mind that if you switch from nVidia to ATI or vice versa, you should carefully sweep your system to ensure all files from the old card are removed, then visit the web site of the new card's maker and download/install their latest display driver release.
Best of luck.

RAM Issues + High disk usage on MSI GE60
Recently I've noticed that my system slowly eats up RAM. It starts off at 21% and can go as high up as 80% or more. When I'm playing games on it the RAM does not clear up properly either, it stays at 50% or so. This was an issue before that I somehow managed to solve, but it is back again.
As for high disk usage, that's been a problem since I've had the laptop.
OS: Windows 8
Processor: Intel Core i7 4700MQ (2.40GHz)
GPU: NVIDIA GeForce GTX 765M
RAM: 8GB Memory
HDD: 750GB
If you need more info I'll provide it.If you open task manager-> performance -> open resource manager / you will see whats eating up your resources
if its windows see if indexing is off
did you installed 3rd party software diffrent than stock ?
how old is your laptop?
its not normal to have such high usage numbers !! i think its a program causing the problems !
if you check your resource manager you will be able to see whats causing it
ps if possible please post a screen shot and ill look into it -
KDE 4.7: very slow and high disk usage
Since upgrade to KDE 4.7 on my i686 laptop, my system behaves weirdly. I noticed a slow down caused by a very high disk usage: when the HDD spins the cpu usage reported by the CPU monitor plasmoid is very high (~ 50%), while top reports a very small CPU load. Another strange symptom is that, when I try to close the session, the system freezes for about 15 seconds before the logout/shutdown/restart dialog window appears, again with HDD spinning furiously. If I exit the dialog window and then try to close session again it works smoothly, so I think some caching is at work at second try.
This is very painful since it slows down my workflow. Since now I tried to:
- disable nepomuk, strigi and all that using the nepomukcontroller plasmoid
- disable compositing
- delete .kde folder
- uninstall and reinstall all kde packages
without any benefit. On the same laptop I have dual boot with a 64 bit arch installation, which does not have the same problem, nor has it my 64 bit desktop pc.
Does anyone have similar issues? I don't understand what is it that makes the HDD spin so much, nor how to eventually track it down (are there som HDD usage profiling utilities?). Moreover, why top and CPU usage plasmoid report so different CPU usage stats?
I'm very confused, so any help will be greatly appreciated.Although I'm not having any of the issues as Snack, I have found KDE 4.7.0 to be a very horrible release. In fact, I'm sick and tired of the KDE release notes bragging about killing thousands of bugs each release, when in actuality the first few revisions of each stable release are horrible. When I first upgraded, I ran into at least four really nasty bugs. Although I've worked around some of them, it left a really sour taste in my mouth. Here is what I've experienced:
1.) With a new user or fresh install, there is no wallpaper by default, even if I install kde-wallpapers before I log in, it makes no difference.
2.) Sometimes kwin will crash during log out.
3.) Worse yet, if I exit a full screen game, it will more than likely crash Kwin. This is a problem on my laptop (which has intel video) and not my desktop (which has nvidia video). If I don't remember to disable desktop effects before opening a game, I may run into a problem.
4.) Although my performance is good, it's not great. I would think a laptop with a Core i5 processor and 8GB of RAM would run faster than it is.
I have tested XFCE for a bit, and I do like it alot. However, with XFCE I am unable to browse Samba shares, and that is a huge problem. In addition, I find KDE's applications to be much better than what ships with XFCE, but I question whether they're worth the performance hit. I really love Kate, Gwenview, Digikam, and Amarok. I know you can install those in XFCE, but they feel out of place and then my desktop pretty much becomes a mutt. Not only that, but KDE is full featured, whereas XFCE is not. It's like I have to choose between a stable desktop or a desktop with full of bugs.
I hope that KDE 4.7.1 fixes everything, but historically it's usually the 4.x.2 release that really does the trick. -
Slowed speed, freezes, high disk usage
After I have been on the computer for about 10-15 minutes, it starts to freeze and slow down. I get a high disk usage message from Norton saying that Windows Explorer Exe. is causing this. I also keep getting the same 5 updates even after I have installed them. I have a Compaq Presario SR5602FH Desktop PC Using windows home basic. Also the Hp updater does not open anymore.
Norton is pretty good but you still could have viruses. I don't think you do and I believe it is your hard drive going bad. I would try to run check disk and if your laptop has the utility partition, test your memory and hard drive.

I bought new lenovo ideapad Z400 touch 2 month ago with win8.
last week i upgraded to win 8.1 and recover back to win 8 , since then i have some problems.
When I have the Task Manager open, I sometimes notice the disk usage climbing to 50, 75, or 100 percent, even though there's scarcely any disk activity going on, the laptop's fan is working hard and very noisy and , my proccesor speed is jump high without any progrems on.
I tried almost anything, cheacked for viruses, disable al unneccesry startup progrems, clean boot, buy it still the same.

Hi All,
I have 4 four disks connected to my db server and on disk2, I found very high usage (above 90%) every time. I have only one tablespace BME_DATA on this disk and it has only one datafile.
There are only few tables (less than 50) that are stored in this tablespace but most of them are very huge in size (~ 500MB), and yes most of them have high DML activity also.
I am planning to create another datafile for BME_DATA on DISK3 so that load can be balanced. Please suggest if there is any better way to do the same.
Thanks for your interest.
BhupinderHi Alan,
What version database? have you analyzed the tables
and indexes associated with the datafile on this
disk? Has this problem recently started?I am using Oracle 9.2.0, and all the table including indexes were analyzed today. Recently I have loaded 1G+ of data into multiple tables and yes out of those tables are only causing the problem.
I have only table datafile (BME_DATA_01.dbf) to Diks2, index datafile is located on Disk1.
Now shall I go and add one more data file to Disk3 or is there any memory changes I can do to reduce the bottleneck on disk2.
Thanks again

Does external editings result to higher disk usage?
I've a master non-referenced image (6MB) stored in Aperture. Subsequently, I've modified it using an external editor. After each edition, the modification are stored as separate versions under Aperture.
Is it correct that each external edited version is stored in full size (6MB) each? For example, I've made 4 editions, therefore, I would have used 24MB (6MB x 4) of disk space.When you export an image to an external editor, Aperture gives you a choice of whether to send it as a PSD or Tiff. Tghios choice is made in Preferences. It comes back as a stacked Version, but in reality is atleast the size of your Master. This is something that hopefully Aperture will change in 2.0. You should learn to take full advantage of the modifications you can make in Aperture. Obviously, there are some beyond its capabilities. Hopefully this too will be dealt with to some extent in 2.0.

Very high memory usage..possible memory leak? Solaris 10 8/07 x64
Hi,
I noticed yesterday that my machine was becoming increasingly slow, where once it was pretty snappy. It's a Compaq SR5250NX with 1GB of RAM. Upon checking vmstat, I noticed that the "Free" column was ~191MB. Now, the only applications I had open were FireFox 2.0.11, GAIM, and StarOffice. I closed all of them, and the number reported in the "Free" column became approximately 195MB. "Pagefile" was about 5.5x that size. There were no other applications running and it's a single user machine, so I was the only one logged in. System uptime: 9 days.
I logged out, logged back in, to see if that had an affect. It did not. Rebooted and obviously, that fixed it. Now with only FireFox, GAIM, and a terminal open, vmstat reports "Free" as ~450MB. I've noticed if I run vmstat every few seconds, the "Free" total keeps going down. Example:

Is this normal and I just need to toss another gig in, or what?

High CPU and Disk usage on HP Envy TS 15 j-155nf after Windows Update
I bought this laptop about a month ago and it worked perfectly fine until the second automatic Windows Update. The booting time got very slow and the entire system started to act laggy. Task Manager showed higher CPU usage than usual and Disk usage was sometimes up to 100% with no apps opened or running in the background. I decided to perform System Recovery using HP Recovery Manager. The laptop worked fine again after that, but then the same thing happened. After the second automatic Windows Update I'm back to a slow and laggy computer. I'm performing System Recovery again, but what can I do to prevent that from happening ?
Hi,
There are few things you can check:
i) Check if you have more than one anti-virus installed..Check for Trial versions.If there is any then uninstall it.
(Sometimes it could be that you have an anti-virus and windows defender or security essentials is also installed)
ii) Next try a Clean Boot and check if it makes a difference. If clean boot fixes the issue then it has to be one of the application on the startup which is slowing it down..
How to perform a clean boot
iii) Run HP Support Assitant and check if there are any pending updates..
Note:
If you have HP Support Assistant installed on the computer(The Blue Question Mark) then open it ==> Complete all pending Updates & Tuneups==> Restart and Check. It may solve your problem
Although I am an HP employee, I am speaking for myself and not for HP.

Warranty Void query(High Impotence) AND DISK USAGE 100% NEED HELP!!!
I Have an HP Dv6 pavillion 7011tx. after i upgraded this laptop to windows 8, i observed that the disk usage (in task manager) always shows 100% activity..had an Clean boot, tried all the disk checks and management things . rebooted th pc again with windows 8 but still the problem continues..
i dont think there is any solution to this problem as i have seen many many more other posts similar to this problem
COMING TO MY QUERY,
I think that the problem is with bios config, my hardisk type is SATA but the bios has it set to EF mode currently .
Which has made my pc very very slow The insyde h20 bios sucks!
Bios utlilty doesnt has the option even to change it. Is there any solution to this problem?
PC Configuration:
I5 3rd gen intel processor
6GB Ram
600GB HDD
CAN THIS CONFIGURATION ACHIEVE A 100% DISK USAGE EVEN IF NOTHING BIG IS RUNNING IN BACKGROUND?
I AM THINKING TO BUY AN SOLID STATE DRIVE, i hope that it will resolve the problem as it is compatible on both the mode. I will extend my HDD with SDD!
Can i do it myself or shall i have to go to HP CENTER.
DOES MY WARRANTY GETS VOID IF I OPEN THE LAPTOP BACK FOR THIS ?
REPLY ASAP (URGENT)Hi,
Disk Usage 100% does not mean disk full but there is task which is doing a lot of i/o during that time (probably swap/page file). If nothing using i/o, the number should be down to 0% as shown:
Now, I start a download, you can see both disk usage and Networks activities:
In your case, the utility may do a lot of i/o to the swap/page file. My suggestion: stop it or BUYING MORE RAM.
Hope this helps.

Windows 8.1 100% Disk Usage/High CPU. HELP!!!
Can an expert possibly assist me in identifying what is causing my HP-G72 laptop to encounter severe CPU/Disk Usage issues??
I have zipped the folder containing the results from the WPT and uploaded it to my OneDrive but it will not let me put the link in the body of this post.
Please Help!You can include a link by replacing http:// with xttp://
In order to diagnose your problem you will need to download and install the below
Install the WPT (windows Performance Toolkit)
http://www.microsoft.com/en-us/download/details.aspx?id=30652
Help with installation (if needed) is here
When you have, open an elevated command prompt and type the following
WPRUI.exe (which is the windows performance recorder) and check off the boxes for the following:
First level triage, CPU usage, Disk IO.
If your problem is not CPU or HD then check off the relevant box/s as well (for example networking or registry)
Click Start
Let it run for 60 secs or more and save the file (it will show you where it is being saved and what the file is called)
Zip the file and upload to us on Onedrive (or any file sharing service) and give us a link to it in your next post.

SA520W - High memory usage, possible fix in 2.2.0 firmware?
As suggested by Thomas Watts, I'm starting a new thread to discuss the new SA520W firmware (2.2.0) and a possible resolution to high memory usage I'm experiencing on my network.
My current setup is: 16Mbit DSL > SA520W > SA300-10, all with stock settings (no fancy VLAN's etc.)
I have 4 CentOS 5/6 servers and a Windows 7 Ultimate station connected to the switch. I use CIFS to connect from Windows station to the other Linux servers and send large files. I currently notice the following behavior:
When the file transfer starts, the Intel 1Gbit NIC is nearly saturated, hitting 115MB/sec. After few seconds, the data transfer comes to a halt and the transfer speed drops to around 50MB/sec. If I check the memory usage before the file transfer, it is approximately to 50-60% (on a fresh router reboot). Every time I send large files to other machines, the router memory consumption increases and it does not lower after a reasonable delay. I end-up with high memory near 90% and the only solution I have is to reboot the router in order to bring it back to 50%.
Now, Thomas told me that this is simply a cosmetic issue, the memory is not actually 90% used. Yet, when the memory hits this threshold, I'm not capable to send files are normal LAN speeds I'm used to. Rebooting the router allows me to send only ONCE (and for few seconds) data at the expected LAN speeds.
I would apreciate any input from Cisco engineers as well other users who experience the same issue. I would also like to know if any related work was done into 2.2.0 firmware and when we expect to have it released to users.
Regards,
Floren MunteanuHi Tom,
See below the answers.
Are you currently running the 2.1.71 code?
Yes
Are you using IPS?
No, the LAN is for internal use (no external users allowed)
Are you using Protectlink services?
No
Hardware wise, I did not changed anything on machines. All boxes have dual Intel EXPI9301CT NIC's (LACP was planned) but I currently use single connections for sanity reasons (disks won't allow greater speeds anyway). Previous to Cisco, I used a Netgear ProSafe router + switch which did not encountered the issues I mention. Honestly, at first I thought I'm dealing with some stupid disk issues on Windows. So I ran a quick test and the stats are proper:
> winsat disk -drive c
> Disk Sequential 64.0 Read 109.62 MB/s 6.5
> Disk Random 16.0 Read 2.47 MB/s 4.4
> Responsiveness: Average IO Rate 2.12 ms/IO 6.9
> Responsiveness: Grouped IOs 8.34 units 7.4
> Responsiveness: Long IOs 5.59 units 7.7
> Responsiveness: Overall 46.63 units 7.1
> Responsiveness: PenaltyFactor 0.0
> Disk Sequential 64.0 Write 117.03 MB/s 6.7
> Average Read Time with Sequential Writes 6.977 ms 5.3
> Latency: 95th Percentile 32.720 ms 3.0
> Latency: Maximum 118.231 ms 7.6
> Average Read Time with Random Writes 13.346 ms 3.7
> Total Run Time 00:01:39.50
As I mentioned before, everything is pretty much stock on router/switch settings. If you have any tips that allow me to identify the cause, I would appreciate the input. What puzzles me is the speed drop and quick memory usage increase. It occurs 7-10 seconds after the transfers begins. It looks like the data transfer hangs for a very short period of time (less than half of second) and the transfer speed decreases from 110-115MB/sec to 50-60MB/sec. The transfer is completed at this speed. No matter how many other files I try to transfer after, the speed won't go higher than 60MB/sec. If I reboot the router, I get the same cycle. -
Hi,
Before everything, two things:
1. I'm not a native english speaker so i may have some problems to speak properly/as objective as i'd like to.
2 . I'm writing in this section because i don't know the cause of my pc issues so i can't categorize them.
Now, my computer is a Toshiba satellite L755-S5244, Windows 7 Home premium 64 bits, Intel pentium CPU B940 2Ghz, 4 Gb RAM, and I'm writing this message using it.
I bought the laptop in December of 2011 and at the beggining it was working normally. Someone else used the computer these last months and he left the pc without antivirus protection; when i installed one (Avast) and start to analyze the pc it suddenly shutted down. It wasn't able to boot, so after some trys to restore/enter in safe mode I finally used the Toshiba Recovery Wizard to get the pc to the original factory settings. The process was sucessfull, so the first thing i did after finish the process was install a new antivirus (this time i used Kaspersky Pure) and the the analysis showed no threats as i expected.
However, before the recovery process i realized of some slow performance on the computer, like talking a bit too long to opening files or menus, control panel... almost anything was opening with a little delay even just after start the pc. This problem continued even after the recovery process. Also, an online game -League of legends- which was working fine when i just bought the pc, developed some issue: the screen and the audio randomly frezees for like 3-5 seconds. These problems seems to be related between each other.
But that wasn't all. After the recovery to the original factory settings, i just installed a few things:
-Kaspersky Pure 2.0, CCleaner (free), Mozila Firefox, and League of legends.
Later I also installed Microsoft Office 2010.
The antivirus showed no threats. The game kept with the freeze thing.
And 2 days ago i was playing league of legends and downloading Skype when the pc suddenly got too slow. I restarted it. After the restart it took a long time to boot, and before the windows login screen loaded there was a black screen where only the mouse was showed; the start-up was slow too, (this one showed a blue screen with the mouse too -but not BSOD-) all this took like 15-20 minutes; that never happened before so i restarted the computer again but the problem was the same: slow boot, slow desktop start-up (let's not even talk about opening something).
I went to the repair menu (f8) and try to restore the system but it didn't change anything. I checked for memory issues but there wasn't. I looked also for starting problems but the repair didn't find anything. All in there was saying: "the computer performance seems normal", but it wasn't. Like entering to windows in normal mode was talking to long, i tried the safe mode. It was also slow but not that much. When i entered, a system restore which i wasn't able to performance before in normal mode popped-up and said that the system was restored sucessfully to the first restore point -just after the factory recovery, but it apparently didn't fix the slow bot issue.
Even in safe mode the software was working slow so i decided to go for the toshiba recovery wizard again, and looked in here, the forums -and the rest of the net- for problems like mine.
This time the Toshiba Recovery Wizard took like ages to finish. 3 hours just for recovering, and like 7 more hours just installing the drivers. The boot/start-up was still slow, so i think this was the cause of the slow recovery because the wizard restarts the computer a lot.
When the factory settings recovery finished, the first boot was slow, also the start up, the programs, the start menu, the control panel, ... everything was slow the first time i opened it. If i keep using the same program, it seems normal, but randomly freezes if i select some option, of press something (like this browser, google chrome, even now when i'm writing this message or before where i was registering into the forums). As obvious, because this slow performance i'm really not comfortable using this computer.
I used the HDD SDD Alert but it says the HDD is working fine (the hard drive doesn't make weirds sounds, i almost don't hear it at all); also i did a PC Diagnostic with the PC diagnostic tool and everything passed the test. I can't think of virus/malware because i did the recovery wizard, twice. I just installed Avast again and it didn't find anything. With the task manager i noticed of a high pc usage (almost always 100%) was showing for a really short moment when/after the computer freezes.
So, i don't know how to solve this slow performance.
The last thing i did was download those speed-up softwares: SpeedUpMyPc, RegCurePro, SpeedyPC pro and Pareto logic Health Advisor. They scanned the pc for free and found like 100 system performance issues, but I'm not able to use these programms to fix the issues if i dont buy them. Also i'm not even sure if that will fix my problems.
That's why i'm here, looking for a way to identify/fix them. One last thing: all this time i've been checking the temperature of the laptop but is never hot -now is not even warm. Now i'm afraid of restarting the PC again cuz i know it will take a long time to get into a kinda stable performance like right now.
So that's all. If you read all this, have my thanks. Also, any help would be really appreciated it.
EDIT:
A new thing happened. When i try to installed league of legends, the setup told me that my hard drive may be corrupted and the file won't copy, i skip it a few times but the installation took a long of time (half hour) and the error kept ocurring. I hope this can may be a clue about what is happening to my pc.Satellite L755-S5244
If you restore the hard disk to its original out-of-the-box contents using Toshiba recovery media and still have trouble, then you know it's not due to software.
the setup told me that my hard drive may be corrupted and the file won't copy, i skip it a few times but the installation took a long of time (half hour) and the error kept ocurring.
In particular, that sort of thing occurs when a hard drive is failing. Time to call Toshiba's tech support at 1-800-457-7777 (from the US) or 1-949-859-4273 (from outside the US).
