Why the swapoff? Most experts agree that having no swap is not a good idea. You waste memory and when memory is filled your system crashes. So why this decision wasting lost of buffer space,

I assume this is for managed? Actually most Java exports would agree that swapping is a very bad idea for Java processes and recommend to turn off swap on a system that runs java.

Java accesses its memory in a "throughput" fashion, meaning there is very little that can be swapped out that is not needed soon after.
