Indeed the 5-instr long fast path is quite fast. Due to the peculiarities of my code, it didn't result in much speedup but I've solved this problem, I can't believe I've overlooked the Gc parameters, I should probably be setting them from within the code. A bit embarrassed about it actually :) I've been thinking whether some kind of doubling strategy would work for the minor heap size. What do you think? Best, -- Eray Ozkural, PhD candidate. Comp.
