So I'd suggest doing what he says.
In particular, use thread pinning to improve
locality.
-qw -qm ?
How's that going to work out when applied to the other
Haskell programs?
I'm sure it does bad things to them.
Yep, earlier in the week I measured the programs using +RTS -N4 -qw -qm which is why I wonder how you would approach programs that have a mix of performance characteristics? Maybe there aren't large Haskell programs like that?
