[jdom-interest] JDOM performance Linux vs. Window 2000

For the best performance on server side with Linux, we use IBM JVM 
1.3.0.  But do not use it for GUI it has problems displaying in KDE 2.x.
JDOM 1.0 beta8 rc1 with Xerces 2.01 works great, is faster and fixed 
some memory overhead we were seeing.

I would expect from a purely JVM standpoint they will be about the same 
performance on win2k and linux.  The issues you will see is Linux 
behaves somewhat better over a longer period of time. Things like memory 
management and multitasking seem to run smoother on Linux than W2K.

There are also a few Linux Kernel patches coming down the road to 
improve context switching between threads that will make the platform 
standout more.

Hope that helps some.
