Virtual machine is slow and stuffers often

I use kali linux in vm and at first when it’s launched it performs okay but then it gets slow after using it for a while.

I gave it 4 processers to use, 8 gbs of ram and 128mb of video memory. Is there anything that I’m missing?

I’m using a asus fx505du laptop by the way.

    One of the CPU-related presentations at VMworld 2019 highlighted the issue, the ESXi scheduler makes some assumptions on how the cores access caches and RAM, that are flat wrong with EPYC CPUs, and that can drop performance hard if you have an affected version.
