JITWatch new set of visualisations on compiler queues

[Chris Newland]

Hey all,

Yesterday I released some new visualisations around the JIT compiler threads and their queues.

Created a release tag 1.3.0 for the new functionality: https://github.com/AdoptOpenJDK/jitwatch/releases/tag/1.3.0

Screenshots of the new visualisations in this tweet: https://twitter.com/chriswhocodes/status/939554917760585729

Video explaining the new features: https://www.youtube.com/watch?v=p0mWUgRcCHQ&feature=youtu.be

These new features allows you to see what was going on in each JIT compiler thread over time and check the length of the queue of tasks waiting for compilation. My thinking was whether JIT resource exhaustion (all compiler threads in use and important methods waiting to be compiled) has a measurable effect on performance.

As always, feedback very welcome!

Cheers,

Chris
