Been there, done that...

I have no idea how JVM manages the memory, but as soon as it gets to
swapping the whole system gets unresponsive (waiting a few minutes for
a keystroke) and the processing takes DAYS.  It means days when I
cannot use the machine for anything else.

I have no problem with letting the processing take a few days as long
as I can still use the system for other purposes.


Don't take life too seriously; you will never get out of it alive.
