Need Java Optimizer

I have written an application complete with Desktop,
split panes, etc. This application runs quite slow. Are there any good Java optimizer out there, preferrably open source?

Both JProbe and OptimizeIt are very good. Neither
is open source. Neither is inexpensive.
If you find such an open source project, please
pass it on.
I turned to books. I like
Java Performance Tuning by Jack Shirazi
Java Platform Performance : Strategies and Tactics
by Steve Wilson, et al
and
Java Performance and Scalability by Dov Bulka
Each has a somewhat different focus and approach.
Each benefitted me and my code.
HTH,

Hey,
less expensive but less effectiv: Run javac with it's optimization parameter
Example:
javac -O myClass.java

-O won't help. It is a no-op on all javac compilers I have used.
