Can you tell us how high you set it? I would recommend at least
524288, and even something like 3000000 if you really need to (I'm
talking in words here)

I've set it to 4M and I think it's worked wonders, the collection time is no more so significant in gprof output (surprisingly) at least now I can identify the real bottlenecks! 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,
