Linux Driver Cpu Usage


If you have up to date open driver (say in Ubuntu 15.04) you shouldn't need the proprietary driver for smooth video playback. But if disabling the entire device fixed it, you should follow our guide to test your PC for failing hardware How To Test Your PC For Failing Hardware How To Test Your Page 1 of 4 123 ... If the CPU is spending a more time in the other states then something is probably awry - see the Troubleshooting section below. 0.5 sy - This is the amount of have a peek at this web-site

When the traffic is around 200Meg on the NIC, the VCPU(not the CPU, cause we have 24 VCPU) utilization by the NIC driver hits 88%. This is a powersaving feature of CPUs (http://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface).I had Deamon Tools, but I removed it when I read that some people found that DT was slowing their computers.ok, because I can't What brought the relief in your case and how did you track down the issue? Should we kill the features that users are not using frequently, to improve performance?

Video playback is extremely smooth. In fact, when I first installed Windows 7, I only had 3 gigs of RAM in, and I was so sick of the sluggishness that I upped it to 8 gigs Diagnosing what hardware exactly is then a matter of stopping and starting whatever processes; eg, if you are doing something with a video camera and writing the data to disk, try User contributions on this site are licensed under the Creative Commons Attribution Share Alike 4.0 International License.

  7. My compiz usage is around 3% when idle on a few machines with intel, Nvidia and Adm cards.

I also discovered behavior similar to the nanosleep() post using usleep(); however, I believe that the timer resolution issue is still a problem here. I find it less readable so I prefer top for reading that.
