Hi,
    I just inherited an old gui application that was implemented using AWT,
I think circa Java 1.1. It is running on a Sun-Blade 2500 running Solaris
2.9 and JRE 1.4.2, so it should be flying, but it's not. In fact, the
performance is horrible. How should I go about improving it? Do I upgrade
to JRE 1.5.0 first? Should I reimplement everything in Swing? Or do I get
a profiler, find out what the heck is killing me, and try to improve it?
ANY suggestion would be helpful. Thanks!

Ric
