You mean more then 4 times - "is accurate" ?!
What makes so big difference?
About incremental gc... I call to System.gc() when
the memory usage is more than a specified limit... But
(as I see from debug output) it do not release any
memory :-( And what should I change in sources to
get incremental GC?
PS I had a look at memory managment of kaffe, but the
scheme is too complex to understand for me :-(
How is the memory organized?
