How to speed up the analysis of hprof files？

[wuzhengxuan]

How to speed up the analysis of hprof files generated by JDK8? Are there any parameters to control it, such as for parallel acceleration?

@wuzhengxuan I have been progressively adding parallelism. The best approach for now is to use a recording tool like async-profiler's flamegraphs, and share the analysis report log. Use this to share a report on where the longest duration of time is. This can help guide where we can make further improvements.

I wrote some general purpose documentation here @wuzhengxuan , please have a read and see if it addresses your question. If you have some more specific questions please let me know and I can add them too!
