Hello,

I have a VPS with 6 AMD Epyc vCores and I want to test its performance with Geekbench 6.

Single-core performance is measured normally/ However, when the multi-core test starts, the following error message is displayed:

TBB Warning: The number of workers is currently limited to 0. The request for 5 workers is ignored. Further requests for more workers will be silently ignored until the limit changes.

The test continues to run, but top shows that it runs on a single core; the results are similar to the single core results.

Should I do something to troubleshoot?

    I found the issue, it was with the configuration of the VPS. my mistake. CPUAffinity was set in systemd.conf . Ideally it would be nice if the error message was more explicit in this case.
