When you forkIO and one of the threads blocks (e.g. on a socket or a readchan), do execution automatically resume on other threads and does the blocked thread consume timeslices while it is blocked?

In GHC: yes, no.

In other words, is there any performance penalty in setting timeslices very large in a server app (where all I care about is throughput)?

No. But there probably isn't much to gain either. Cheers, Simon
