I use this Dell XPS laptop as a development machine. It has a 6 core i7 (12 logical procs) in it. 32G RAM. I have VMware Workstation 16 Pro, version: 16.2.4 build-20089737. I set up a VM of CentOS-7 with 2 cores, half the available RAM of the host.
At first, the VM worked just fine. Lately though, after I power it on and work for ~10 minutes the performance slows to a crawl; I can barely type on the command line without extra letters showing up…horrible.
I verified I had not run out of space, plenty of that. I tried increasing the cores of the guest to 4 from 2, the problem persists. The only thing I note is that it doesn’t seem to matter what I’m doing; meaning, I can power on the guest and let it just sit there and after ~10min if I then start to try something the performance has already dropped off.
I checked dmesg on the host for anything ominous but didn’t see anything unusual.
What else is there to check to isolate some causes?
