Subject: CPU stats on multi-core?

Hello,

I played a bit more with my CPU using the --fork option and I'm a bit
unsure if it's working properly. I tried for example some unix MD5 hashes
on 8 cores and I get this stats:

Well, I assume that each ETA is per virtual core, correct? If not, it could
complete more than 100% sum them all together.

The weird thing is, all my virtual cores are exactly the same, why they
have too much discrepancy from one to another?

I don't have other applications or programs running, however, we see for
example some cores that executed only 0.04% while other executed 32.68%.

Very weird, I was expecting them all to run pretty close one to the other.
Is there a way to fix it?

I tried even a bigger word-list and the discrepancy is so big that even
exceed 1 week.

Is there a way to print a single stat line for all cores? I think it would
be less confusing.

Thanks.
