I've installed Boinc on a new virtual machine to test some things and, when i run benchmarks i have this message:
FP benchmark ran only 1.92187 sec; ignoring

No whetstone or dhrystone.

Apps run correctly, nevertheless.

performance will always be (much) slower in a VM than when ran natively.

Is this something to do with the virtualisation? I know that benchmarks under WINE are I think about a quarter of what might be expected though you can get an accurate benchmark there by telling BOINC to use only one CPU, then manually running benchmarks from the manager after which you can let it use however many cpus it wants. I will have to look at my VB to see if it suffers the same issue.

You can tell computers are a hobby for me and not my profession. Had to look ESXi up to see what it was.

ESXi is the free version of enterprise virtualization from Vmware.
