for some reasons, while copying a 13 gb file over the network (accessed from servernamee$ to my C drive, the CPU usage is going close to 100%.
When I look at task manager, I see System using more than 30% of the CPU, SMC.EXE is using between 15% and 18%...
Does anyone have an idea why system is taking that much CPU?
I tried disabling the antivirus to reduce the SMC.exe process, without success..
I've just installed the Windows 7 RC on my lab-pc. It's a 2,4GHz Celeron, 1GB DDR-RAM, everything installed on some old 160GB PATA-HDD. Two hi-speed USB Keys are used for ReadyBoost (love that feature).
Everything works like a charm, except the file transfer from my WXP machine.
I mount the SMB share (which is on my WXP) from the Windows 7 machine and start to copy some big files. Transfer speed is ~1MB/sec on 10MBit, ~5MB/sec on 100MBit and ~11MB/sec on 1GBit. When I start file transfer the CPU load pops up to 50% while 10MBit is active, for 100 and 1000MBit it jumps to 100% and stays there until the transfer is over.
Since I read about IRQ issues I tried some NICs. An onboard SiS-900, an RTL8139 based PCI card and an Intel Pro 1000/MT Desktop adapter. I thought that - at last - the Intel NIC should stop my problems as it comes with IRQ moderation and TCP/UDP checksum offload.
None of these 3 NICs solved my problem.
All these NICs run on the driver Windows 7 has found for them. None of the vendors had a special driver for me.
What I tried to do in addition:
- disable Windows 7 firewall
- disable IPv6
- disable QoS
- tried another CAT5e cable
- restart the switch (Netgear GS108)
- hit the whole machine
Note of the above worked.
I just hope you just have an idea left for me. Just ask if I missed out some details.
I have noticed when Iam downloading at full speed of 1.8MB/s on Wifi or LAN there is high DPC/IR (Deferred Procedure Calls and Interrupt Requests) CPU usage - and when transferring files in or out to USB hdd.. i sometimes get pops & clicks in audio too - the CPU is a Turion 1.8Ghz x2 with 1Mb L2 cache and 2Gb of ram, DPC/IR can only be seen using Resource Monitor in windows 7 (type 'resource monitor' into startsearch) or using Process Explorer software, I dont know much about DPC/IR but as far as Im aware it handles errors or something like that and I was told it should never even go beyond 1% cpu usage - its more noticeable on laptops as these have CPUs that arent as powerfull as desktops and have wifi, it seems to be worse with wifi. it causes latency problems in windows too and things like audio playback get pops & clicks and windows & apps become sluggish.
What brought it too my attention was the CPU fan on my laptop was on all the time and windows seemed to be sluggish when I was downloading even though uTorrent was just using 3-5% CPU, I noticed the total at bottom of Task Manager seemed to be more than what would tally up in the window, it was when i used resource monitor that I seen it.
WiFi @ 1.8MB/s = 10-15% DPC/IR cpu usage
LAN @ 1.8MB/s = 5% DPC/IR cpu usage
Copying Files to USB HDD = 15% DPC/IR cpu usage (this test was odd as it was some time ago i done this one, but I remember it was either IN or OUT that had the increase, probably IN (and OUT was <1%) , I tried SDcard too and got varying results)ive even seen it max at 40% when downloading on wifi and copying a file in/out too usb hard-drive at the same time...
After about 24 hours of booting my computer, I have seen my DPC Latency spike tremendously. At first, I thought this was an issue with my network card (since disabling it would drop DPC Latency), so I bought a new card. The problem didn't go away, so I realized it was something else. High DPC Latency is a problem since it causes audio and video lag.
As I troubleshooted the issue, I have realized the spikes were caused from network activity. For example, when I am seeding [not necessarily uploading] many torrents or am loading a website, it shoots up.
Does anyone know what may cause this and how I could prevent it?
what file to remove to when the CPU alerts you of high usage.
View 3 Replies View RelatedFor the last week or so, my network traffic has seemed to be related to some pretty sever spikes in my CPU usage. These spikes are causing extreme stuttering in my music playback, freezing of my cursor, and other symptoms of a really laggy computer. This pretty much occurs whenever I use the internet in any way. The worst spikes are when I'm loading webpages in Google Chrome and seeding on uTorrent, often freezing my cursor and music for several seconds at a time, though they're not limited to those two softwares. More recently, it seems that when I am loading pages in a browser, it's spiking CPU usage in bother the browser and even more so in the System process. It's becoming a real issue to use my computer.
On a side note, I've noticed that the displayed memory usage in the task manager (2.74 GB) is way more than what all the processes appear to add up to, usually by more than 1 GB.
I just installed windows 7 ultimate sp1 - Like the title says I'm seeing 35% cpu usage with nothing going on. I googled around and ran traces to see which driver it was, turned out the ahci driver was doing it. The USB driver showed similarly high latency but that can be delt with later. Most forums recommend upgrading your drivers but this problem has stayed constant both with microsoft's stock drivers for everything and after running windows built in search for drivers even after I manually grabbed the latest drivers for everything. url...BIOS is up to date4 GB RAM - Corsair something or otherEVGA Geforce 8800 GT450W psu1 DVD burner (sata)5 hard drives (sata) plugged into all but the first sata port because that caused nothing but headaches for me. Update - switching from AHCI to IDE in BIOS fixed the problem.

View 4 Replies View RelatedSince Jan-Feb of this year I have encountered the following issue while trying to play games on my laptop.
Abnormally High CPU Usage
Extremely low FPS - After 5-20 Mins of play.
Extremely High latency to servers - from 300 - 900 after 5 - 20 mins of play.
The thing is all of these started 1 year after I been using this laptop, after a full year of everything running flawlessly all these issues kicked in after I performed a clean install in Jan., I even performed one in Feb. and one 3 weeks ago

Adapter Description ATI Mobility Radeon HD 5400 Series
Adapter RAM 1.00 GB (1,073,741,824 bytes)
Whenever I am on my computer My RAM usage is really high. More than I think I could ever use up! When I am not on an App/ Browser my RAM Usage is still above 50-60%. I also think my internet connection has something to do with it because when ever I try to load a video/website it takes more than 10minutes to load a 30 second video!
View 1 Replies View RelatedI have a very high cpu usage for some reason. I wont even be at my computer and I can hear it working away.Take a look at the picture. I wasn't really even doing anything. I have itunes open, mozilla, skype but not doing anything.I've looked at the processes and it seems normal. Firefox is always top.
View 5 Replies View RelatedI don't know if I'm just overthinking/worrying too much about my laptop, but my CPU usage lately seems to idle between 10 and 30% even when I'm not doing much. I've noticed that TeaTimer.exe (Spybots real time protection) seems to hog some of this, and I'm not sure if I need it since I have Malwarebytes and SuperAntiSpyware installed. I've also noticed Firefox to be very laggy but this could well be a seperate issue. Also on startup my computer does seem to take up to five minutes to settle down after logging in.What can I do or what should I be checking?

I just reformatted my computer to windows 7.
And i'm kinda disappointed on its performance compared to some reviews i've seen in the web.
It seems that my computer consumes alot of RAM if i'm not mistaken.
Here are my processes and memory usage:
i have 4gb ram installed, but i installed win7 x32bit.
So when i on photoshop or other program that uses alot memory, the ram usage goes to 1.6-1.8 GB.
And during that time i felt some lag.
Lately, the cpu usage on my laptop goes very high without no reason. It sometimes bursts from 10 to 100 percent without any apparent reason. Looking into the task manager and sorting the procceses by cpu usage reveals that no single process uses very much cpu,instead about 10-15 percent is used by multiple services each.I run an Asus laptop k73s with an i5 2430m proccesor, an nvidia gt540m, 4 gigabytes of ram and windows 7 ultimate 64 bit. I tried everything from doing registry cleaning and repairing to disk formatting and virus and malware scans. Each attempt to no avail.

I'm using Windows 7 premium with 3GB ram. please help! because i know that this is not normal
I was using vista x86 up untill windows 7 came out, it was the I decided to go for my first x64 operating system. I have an i7 and 3gb ram.
Ever since I've moved over, games take up a stupid amount of memory, they'll go to 80 - 90%. I recently decided to install Crysis Warhead as I never got round to completing it, last time I played it I was on vista x86 and it ran fine. However now, it takes forever to load and/or freezes because there's no memory left.
I've tried setting the page file at 200 - 1024, 1024 - 1024 and turning it off, none of that makes a difference. I tried increasing it to 4096-4096 just out of curiosity, that managed to load the game, however, while I did have a constant 50-60fps I was lagging really badly and had 91% ram usage.
Am I missing something here, does anyone else have this issue?
I have a Lenovo laptop with Win 7 Pro.
When I leave the laptop on standby, and come back to it after 10 minutes, the fans are blowing loudly. I have a CPU gadget which monitors CPU usage, and I see that right when I resume from standby (move the mouse), CPU usage drops to normal.
At first I thought Security Essentials is doing some scanning or windows is indexing some files, but this happens every time the computer is idle for longer than 10 minutes. I have a suspicion that my laptop could be part of a bot network.
I think it's only a recent issue... Look at the "Physical Memory" at the bottom. url...As you can see the only program running is NOD32 and Chrome.

Why is my pc going so slow?
system: inspiron 1420 windows 7 issue: suddenly slow system (cpu usage usually raises to 100% when opening any programs such as a web browser, then dips back down when everything is loaded enough) attempted solutions: anti-virus, malware, anti-spyware programs | chkdsk, sfc /scannow |memory diagnostics | adjusting appearance | using task manager to locate highest cpu usage program (none of these attempts have identified the problem.)my system which is a dell inspiron 1420 windows 7 was recently given a clean install to windows 7 from vista. everything was going fine for about two weeks when suddenly everything started to become sluggish.now when i for instance open a video on Internet, the video will buffer, and while that's happening the audio that plays sounds like a droning machine as if it was being disconnected from the matrix, ha. after the video loads enough, the sounds remains normal. not only that, but the mouse will stop, stutter, freeze, then continue after the video has loaded enough to where the mouse can move again. i'm also experiencing freezes on this machine, and usually when the computer does freeze the mouse pointer disappears.
i have already tried many things, such as running anti-virus, malware, and anti-spyware programs which had all come up with no threats. i've run chkdsk, sfc /scannow (which did in fact find corrupt files, but they were unable to be repaired. if anyone can tell me how to repair those files that cannot be repaired, i would appreciate it), and i've also done memory diagnostics, all of which are not identifying with the problem i'm having.
I have a Sony with win 7 64-bit and 4 gigs of ram. About a month ago I started to notice my computer running slower. When I checked windows task manager (performance) it was using 3.5 gigs of my memory. I restarted the computer and it went down to 1.5. I have on occasion had to restart twice to get the memory down. I have run virus checks and reg cleaner but it still occurs.
