Aaron,

I believe what you are seeing is to be expected and is the default 
behavior for the JVM implementation on Windows.  By default, the Java Heap 
will consume up to half of your physical memory.  If you want it to use 
less, you can constrain it using command-line switches on the shortcut. 
With WDSC, I believe you can also enter these in the wdsc.ini file in 
C:\Program Files\IBM\WebSphere Studio folder.

The JVM will not bother to free up unused memory (garbage collect) until 
it has to.

This article has a more thorough explanation.

I did not see much benefit, but in my case I was trying to speed up WDSC, 
I was not trying to make it use less memory for multi-tasking.

Good luck, and let usk now if anything helps.

I just upgraded my memory in my laptop to 1Gig in an effort to satisfy 
WDSc
5.0.

Just took a look at my system tasks and javaw.exe is using 429MB of 
memory!
I have 8 iSeries source members open and 1 .html file.  That's it!  Is 
this
for real?  YIKES!  Is there a machine big enough to run WDSc 5.0 without
having to have it be the only app running on the system? 

All I can say is ouch.
