Issue created Aug 06, 2007 by guest@trac-guest

Process creation and communication doesn't scale linearly

Creating processes (with forkIO) and communicating between them (with putMVar and takeMVar) does not scale linearly. For 10000 processes creation takes 8us, but for 100000 it takes 60us. Even taking the increased GC into account it's highly non-linear.
