Unfortunately, we need the extra heap space for some things that we are doing within our custom data visualization apps. We started getting outofmemory errors on our 7.1 midtiers which prompted this 7.6.0.4 upgrade effort.

BMC states that the 32 bit jvm is about 45% faster than the 64 bit. Your choice, just want to be sure you see the cost from both sides.
