Memory allocation really only helps in the event of caching information that
will be used extensively, so allocating more memory really doesn't have any
effect if the application doesn't use it. You could allot 1GB, but if javac
only requires 100 MB, it will never gain any advantage from having the other
memory reserved. If anything, it will most likely suffer a performance
degradation if your operating system is trying to multi-task between your
compile process and other background processes that are starving for memory.
I would try to evaluate what the largest block of memory you require for
compiling, reserving a good 30 to 40% more space for future development, and
let that roll. Anything else would most likely be consuming resources
unnecessarily.

Right, but does say allocating 768 MB of ram instead of 512 make any
difference?  Should it?

Doesn't matter I'd think if you're not getting OoM errors. --DD

On our systems here, we all have 1 GB of ram - how much should I allocate to
the lengthy compile target?  When does it not matter anymore?
