So, if you've chosen 256m conservatively, taking your input data into account, the patches don't help. - The second patch is a simple hysteresis control that mitigates rapid heap size yo-yo-ing. Using -:hs0 prevents that completely. Also, there won't be that much speed-up if the major-gc-time to total-run-time ratio is low to begin with.
