Subject [jira] [Commented] (SOLR-3932) SolrCmdDistributorTest either takes 3 seconds or 3 minutes.

Mark Miller commented on SOLR-3932:
-----------------------------------

So doing other things to relieve the stress also hide the issue - eg raising our update buffer
size...

I pinged yonik about this to see if he had any ideas and he brought up that I should try the
NIO jetty Connector impl. For various reasons we don't currently default to it.

That actually seems to work much better. We have advanced a couple Jetty versions since the
Connector impl was chosen, so perhaps it's time to come back to this choice.

> I've looked into this a little in the past, but had not come to a conclusion. It really
bugs me because it doubles my test run time from 3 minutes to 6 minutes when it happens.
> I've been looking into it today and I think I've tracked the problem down to mostly test
bugs. One real bug around distrib commit ordering was also uncovered.
