This is a test framework that spawns system commands. My guess is the Haskell accounts for a few milliseconds of execution per hour. Running two system commands in parallel gives a massive boost.
A related question I wanted to ask. Is there any way to have my Haskell program support -j3, which is equivalent to +RTS -N3 -RTS. At
my own program creates a lot of parallel threads without using -N
the secret is using of forkOS plus C code in threads. since you spend time in system calls this should also work for you
Are you sure you need forkOS, and not just forkIO? Why? Cheers, Simon
