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.
Feedback and patches welcome!
