Mark Miller commented on SOLR-13796:
------------------------------------
FYI, my method for speed up is simply to run a test with yourkit, find silly
slow spots, address, repeat.
Will try and share soon - amongst a few months of travel and time away :(
> Fix Solr Test Performance
> -------------------------
>
> Key: SOLR-13796
> URL: https://issues.apache.org/jira/browse/SOLR-13796
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Mark Miller
> Assignee: Mark Miller
> Priority: Major
>
> I had kind of forgotten, but while working on Starburst I had realized that
> almost all of our tests are capable of being very fast and logging 10x less
> as a result. When they get this fast, a lot of infrequent random fails become
> frequent and things become much easier to debug. I had fixed a lot of issue
> to make tests pretty damn fast in the starburst branch, but tons of tests
> where still ignored due to the scope of changes going on.
> A variety of things have converged that have allowed me to absorb most of
> that work and build up on it while also almost finishing it.
> This will be another huge PR aimed at addressing issues that have our tests
> often take dozens of seconds to minutes when they should take mere seconds or
> 10.
> As part of this issue, I would like to move the focus of non nightly tests
> towards being more minimal, consistent and fast.
> In exchanged, we must put more effort and care in nightly tests. Not
> something that happens now, but if we have solid, fast, consistent non
> Nightly tests, that should open up some room for Nightly to get some status
> boost.
