3.1.5 Performance analysis tools (optional)

As you formalize your designs and requirements it is often helpful to drop into a performance measurement tool to see where your code is spending its time. Two popular commercial tools for Java optimization are:


OptimizeIt, VMGear (http://www.vmgear.com)

JProbe, Sitraka (

)


You can also use the free (but harder to interpret) performance measurement capabilities of the Java 2 JVM. See the documentation for the java –Xprof argument for details.
