I think this is problem with the java environment on windows. on 32bit
it can actually never grow past 2gb. how well the 64bit works I do not know.

however, you might want to have a look at the bandwidth to whatever
storage you have. the disk is a bottleneck to take into consideration.
you want gigabit if you have a network, and maybe even RAID if you run
locally. at the same time, make sure you use good a image format. some
sort of compression is a requirement, lossless at minimum.
