Michael Stack commented on HBASE-23779:
---------------------------------------
Latest patches add MAVEN_ARGs to our yetus hbase personality passing "-T0.5C"
which tells maven to run with 0.5 times the count of CPUs of threads. Default
is one thread. This change improves build times AND test run times. I got the
trick from a [[email protected]]
> Up the default fork count to make builds complete faster; make count relative
> to CPU count

> Key: HBASE-23779
> URL: https://issues.apache.org/jira/browse/HBASE-23779
> Project: HBase
> Issue Type: Bug
> Components: test
> Reporter: Michael Stack
> Priority: Major
>
> Tests take a long time. Our fork count running all tests are conservative --
> 1 (small) for first part and 5 for second part (medium and large). Rather
> than hardcoding we should set the fork count to be relative to machine size.
> Suggestion here is 0.75C where C is CPU count. This ups the CPU use on my box.
> Looking up at jenkins, it seems like the boxes are 24 cores... at least going
> by my random survey. The load reported on a few seems low though this not
> representative (looking at machine/uptime).
> More parallelism willl probably mean more test failure. Let me take a look
> see.
