Default worker windows: one per physical/logical core?

I recently got access to a machine with an i7-720QM processor, which has four physical cores and eight physical ones. I am under the impression that Prime95 can only run one worker window per physical core. However, when I started up Prime95 for the first time, the default number of worker windows to use was eight.

Is it "safe" to use eight worker windows in this case?

It can run a worker on each logical core, but it's so slow that it's best for throughput to let each worker have its own physical core.

Yeah, it was indeed very slow when I used eight worker windows. Four it is, then.

Thanks.
