[Haskell-cafe] ANNOUNCE: ghc-gc-tune: a tool for analyzing the impact of GC flags

Inspired by a comment by Simon Marlow on Stack Overflow, about the time and space tradeoffs we make with garbage collection, particularly with a generational GCs, I wrote a small program, ghc-gc-tune, to traverse the garbage collector variable space, to see the relationship between settings and program performance. Given a program, it will show you an (optionally interactive) graph of how -A and -H flags to the garbage collector affect performance. http://donsbot.wordpress.com/2010/07/05/ghc-gc-tune-tuning-haskell-gc-settin...
