[K12OSN] Java on Linux slow, any ideas?

[Todd O'Bryan]

I'm running BlueJ, a fairly modest teaching IDE in my lab, and it's
slow as molasses. Even slower than Eclipse, if that means anything to
you.

If I had to guess, I'd guess that every student is getting their own
copy of the program and the needed libraries rather than sharing them
with everyone else, but I'm not sure how to verify that or what to do
about it. The shell script that runs the program is:

#!/bin/sh
APPBASE="/opt/bluej"
CP="$APPBASE/lib/bluej.jar:/usr/lib/jvm/java-6-sun/lib/tools.jar"
"/usr/lib/jvm/java-6-sun/bin/java" -cp "$CP" bluej.Boot  $*

Anybody have any ideas about how I could maybe speed it up? It's
making Linux look bad to my AP Computer Science kids.

Thanks,
Todd
