Allocation efficiency - and to make sure you actually get the memory
when you need it!

As we said before, no - unless you're running with the Windows boot option that
specifies use of a 3 GB user process space

Not likely. The most you can set the heap to on 32-bit Windows is around 1.5

By default Java 1.5 defines the maximum heap size to physical system memory
divided by 4.
You can change this on the java command line by using: java -xmx512m
Sets maximum heap size (the largest the heap can grow to - where objects
reside), to 512 meg.
