I just installed VirtualBox and setup my first guest, Debian 8.5 with Gnome. My CPU usage while the guest is idle is 17-20%. I am new to VirtualBox so this may be normal, but it seems high to me.
System Specs:
Intel i7-4790k 4.00GHz
32GB RAM
Nvidia GeForce GTX 960 4GB
120GB SSD (host and guest on this drive)
I gave the guest 1 CPU and 2GB RAM. Installed VirtualBox Extension Package and Guest Additions.
Is there anything I should change to get better performance and lower CPU usage?
Any suggestions are greatly appreciated!

Re: Debian guest CPU usage 17+% idle
It looks like the cause for this is due to running in software rendering mode because the guest has not had the 3D acceleration enabled in the guest settings. Enable it and see if the CPU load reduces.

That seemed to do the trick! Besides when the VM was booting and a quiz spike when some programs are opened, CPU usage hasn't gone above 5%.Perryg wrote:It looks like the cause for this is due to running in software rendering mode because the guest has not had the 3D acceleration enabled in the guest settings.

Thanks for your help!
