I am wondering about recommendations for the best profilers on the Mac
a) For a Java 1.4 program
b) For a Java 5 program
Integration with Eclipse preferred, but not required. Need to
measure actual method invocation times accurately, hopefully down
to microseconds if possible or at least milliseconds, and not
statistical sampling.
I have had very good results with JProfiler from e-j technologies.
It has both sampled and instrumented options, and does very good time
and memory profiling. The heap walker is also well designed, and has
saved me effort.
It has an integration plugin for Eclipse, IIRC. I can attest that
the IDEA integration worked the last time I tried it, though I
usually go through the JProfiler app itself. I have used it both
with 1.4 and with 1.5.
Others have recommended YourKit and the NetBeans profiling module,
but I have not tried them myself. They also seem competent, and
given that NB is free, it might be a good place to start.
Shark can profile Java as well, but it only offers sampled, rather
than instrumented, time collection, so it does not meet your stated
needs.
