hi,

i was wondering whether there is a mechanism in ruby where we can tune  
certain GC params like heap size etc and collect the stats like pause  
times etc in ruby. i would like to analyze the GC performance of ruby  
with varying certain params.

all i could find was a GC.start and stop which is of no use to me

tx,  
V

Only by recompiling gc.c.
