Which Hypervisor?

It looks like right now there isn't much difference. This is on Parallels 16.0.1 running macOS Catalina 10.15.7 and Ubuntu 20.04. I was hoping one would be better about releasing unused memory but that does not appear to be the case.

CPU Benchmarks:
Geekbench5 shows that they are pretty much the same
1223 vs 1229 single core; 7246 vs 241 mult core

Memory Usage:

Parallels Hypervisor, after build android and disk cache cleared
real memory used: 7GB

Apple Hypervisor, after build android and diskcache cleared
real memory used: 7GB

If someone knows of a way to release this memory without rebooting, it would be very helpful, especially when running multiple VMs.
 
Yeah, my experience is the same (did some benchmarking and stuff some time ago). I chose Apple's hypervisor (I think it is bhyve based, by the way) since it is natively supported by OS and which means that I am getting less surprises from the system when going through sleep/resume cycles, etc. However, truth to be told I never experienced any issues with the Parallels hypervisor too. Well, I did not measure the battery life under both of them, but my perception is that it is better under Apple's one.
