I have seen some proposals around here for SoC projects and other things to try to improve the latency of GHC's garbage collector. I'm currently developing a game in Haskell, and even 100ms pauses are unacceptable for a real-time game. I'm calling out to people who have seen or made such proposals, because I would be willing to contribute funding and/or mentor a project that would contribute to this goal. Also any ideas for reducing this latency in other ways would be very appreciated.
In my experiments with real-time audio signal processing I could always find a culprit for buffer-underflows other than the garbage collector. Sometimes it was a space leak (e.g. by adding a finalizer to the wrong object), sometimes incorrect handling of time differences, and when working with LLVM it was frequent recompilation of LLVM code.
