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!

No. Last I checked, 1.5 was still beta.

Probably not at this point.

That sounds like the right approach.
ANY suggestion would be helpful. Thanks!

Rumor has it that Sun has made performance improvements
in their stuff over time so if you just recompile/run it with
J2SE 1.4.2 it might be fast enough with no real work on your
part. Keep the original though. I would stay away from 1.5
since it is not yet officially released and if there is a
problem it might be more complicated if you can't trust
the compiler/vm
Ok, it sounds like trying a profiler is the way to go. Does anyone have a
suggestion for one I can use?

You can spend a heck of a lot money very quickly here. Try out some of
the free stuff first. See http://mindprod.com/jgloss/profiler.html
for lists of both.

Thanks for all the advice so far. One more thing. Someone suggested that I
might want to move it to Eclipse's SWT, and that there are tools to do this
in an automated way. Can anyone tell me anything about that? Thanks.
