1589	Process creation and communication doesn't scale linearly	guest	simonmar	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.	bug	closed	normal	6.10 branch	Runtime System	6.7	fixed		lennart.augustsson@…	Unknown/Multiple	Unknown/Multiple	None/Unknown	Moderate (less than a day)
