I'm running the demo on suse 9.1 pro.
Just have one project open and its at 662 megs ram utilization for the
jbuilder executeable and 234 megs for the jbuilder java binary.

Sounds like a memory leak more than just a high system requirment for the
IDE.

First check the VM parameters for both JBuilder and the executable.

Process accounting on Linux takes a bit of getting used to.

When you start Java with, say, -Xmx512m (as I suspect the enterprise 
version does), Java memory-maps 512MB worth of VM (which is what you see 
in the ps display as the "process size"), though it actually touches 
only a small part of that to start with.

Also, any files that are memory-mapped using java.nio.MappedByteBuffer 
show up as VM usage.

How are you measuring the usage? "top" is the usual tool. In top, the 
"Size" is the VM mapping size, but that's a misleading indicator. "RSS" 
is the true indicator of memory usage, the "Resident Set Size".  See 
what that value is..
