It had better not appear.  You have a heap as big as the total memory
many people have in their computer.  It probably never collects at all :-)

So with the GC params set to the defaults, 3.3 needs 1 friggin' GB to be
close to but still slower than 3.2 with only 32MB!?  That looks really
sad...

Were these timings you did avarages or did you do one run for each?
