I built a new Linux machine to be able to handle multitasking and running multiple virtual machines. It's an AMD 8 core 3.5GHz processor with 16MB Total Cache, 16GB 1866 DDR3 RAM, 1TB HD and a GForce GT 730 4GB 1600 DDR3 Graphics Card. I have VMware Workstation 12 running with 3 guest machines. Each machine has 1GB RAM, 1 CPU/PROCESS, 512MB Graphics, and over 70% drive space to spare. The guest run fine.
When I check system CPU and RAM usage on my host after my host slows down to a crawl, the CPU usage is at ~99% and ram at ~20%. The system has run with no problems with CPU usage at over 210% (observed using
top command) while running 1 guest VM. I haven't had any other problems with the system.
Is there something else I haven't measured that could cause the system to crawl when ram and cpu hasn't been maxed out (other than GPU...see update)?
Update: It looks like this may have been an issue with my Nvidia settings for my graphics card. I changed PowerMizer from 'auto' to 'Maximum Performance' and I'm monitoring with system monitor and the graphics card with
nvidia-smi and other GPU monitoring tools mentioned here.
