JOP is a 100% pure Java real time graphical interactive profiler. No
native library or executable is required. It provides views with :
thread tree,
and method tree for
time spent analysis,
callee tree for
performance bottleneck identification,
object
allocation tracking with location in callee tree to find
memory leaks,
memory and
objects
allocations monitor.
JOP has
a very low overhead : a profiled application is
running about 1.5 to 3 times slower than its standard speed (highly
dependent on the kind of code). It is derived from the bytecode
instrumentation of the JIP
profiler.
