My 4 core 8 threads ryzen 3 3100 is able to run 8 thread vm running cpu stress test on vmware, without making host system lag.

While virtualbox makes host system choke even with 4 threads.

Something is wrong with virtualbox code.

When i set it to 3 cores it for some reason uses two cores.

It also doesn't show job output in second tty.

I have set atlas dev native to use one core, but sometimes it tries to run it on all cores and uses all of
ram and swap.
My vmware vm is set to use 6144 mb of ram.
When i run atlas dev on virtualbox boinc allocates 4100 mb for 1 core.
https://lhcathomedev.cern.ch/lhcathome-dev/result.php?resultid=3209999

4800 mb for 8 cores

Task eventually falls back and runs without agis_ddmendpoints.json file, but it wastes time in beginning and end.

I was able to install cern root certificate and modify job.xml but it gets reset each time computer restarts.

Looks like version 3.01 needs less memory than previous version.
I think if 8 core Virtualbox vm for 3.01 is set to use 4 gb, then i will set my 8 core vmware vm to use 4 gb.

Why does virtualbox 7.0.6 decompress vdi when multiattaching?
I compacted vdi with "compact /c /s /a /i /exe:lzx" command, but virtualbox decompressed it.
I think vbox 5 didn't do that.
