Reg - Sub Process creation from java takes more time

I monitored memory usage, below are the details.
Heap usage :- 857mb
Virtual memory:- 12.6gb
-Xmx set to 4gb.
I have taken virtual and heap memory usage when Java spawns sub processes.
Sub processes have short life, will be done in milli seconds.
Thanks & Regards,

Do you monitor heap usage and virtual memory size of your Java process? I
would look out for increase (which causes slower for tines).
Also it is generally a good idea to turn on GC logging and look into it if
a java process degregades over time
Just BTW: I think Java would not be the right tool to spawn and control
sich a high number of external processes. Maybe it would be better to hand
that off to a more native component.
