Thanks Peter. That was a great post! I am looking on to your presentation and checking to see if I can optimize my GC. BTW I am using Window XP as my platform, and is there a relation between the operating system word length and the maximum heap size that can be allocated?? Do we have any statistical relation for it?

If I consider my OS to be 32 bit then I should be allowed to set a Maximum heap size 1.5GB which is 1536m (to be in multiples of 512m). If thats the case I am getting error for this statement 

Xms1536m -Xmx1536m. 
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
Press any key to continue . . .
