Subject: Cool new tool for JDK1.2 performance analysis

I've just published a tool I wrote to assist me in performance profiling
of applications I'm developing under JDK1.2. Although I work in the
Linux environment, the tool should (I suppose) work in any JDK1.2
environment.

The tool, JAnalyzeProfile, is a perl script that analyzes the profile
data produced by the "java -Xrunhprof..." output, and I've found that it
does a nice job of fingering hotspots.

The tool is available at
http://www.teleport.com/~nmeyers/JAnalyzeProfile/ .

Be sure to read the caveats at the end of the article. The most
important one is that the tool works well with green threads, but, due
to profiling behavior with native threads (defect?), does not report
usable information when native threads are used.

Enjoy!
