Tom Jenkinson commented on JBTM-2478:
-------------------------------------

 a "Tricks" section to the README.md if the SVG file gets too big. Brendan is working on a Python version of FlameGraph

 https://github.com/brendangregg/FlameGraph/tree/master/dev

which has search support:

 Search -> com/arjuna -> Purple nodes

> Tools and instructions are at:
>  https://github.com/jesperpedersen/perfjava/    <-- CPU sampling
>  https://github.com/jesperpedersen/javamemflame <-- Memory allocation tracking
> Both use Agent_OnLoad/Agent_OnUnload, so better for smaller tests.
