Boinc is running 5 theory tasks simultaneously and so is running them very slowly and they are not using the full system resources

It should not run more WUs that you have cores, so I'm not sure, it could be you set something with app_config.xml?

It can be that the WUs don't use any CPU power as the VM has nothing to do inside the WU, I personally find this to be not so common, you can leave them and they clear out eventually, this the best as it sends the feeback to the project that they should do something, although it bothers me that my computer are not busy. Else as you have done just abort them typically the new WU gets some work.

This setting doesn't work so well for LHC:

2023-10-25 15:14:28 (9812): Setting CPU throttle for VM. (90%). Becuase the VMs don't like the cycling of pause/run.

its better to use use at most 75% of the cpus if you want to limit the max overal CPU use and keep the at most of time at 100%

it could be you have some invalid VMs left over so shutdown BOINC and clean everything out from VirtualBox.

If you want to see whats happening in the VM then you can install the extrsion pack

They normally run for about 24 hours

I think it was the setting that was messing it up
