Ryan Zezeski commented on SOLR-4509:
------------------------------------

I generated the patch from my clone of the git mirror.  If this patch is unacceptable in anyway I'm willing to redo.  Just thought I'd take the easy route first.

> By disabling the Apache HTTP Client stale check I've witnessed a 2-4x increase in throughput and reduction of over 100ms.  This patch was made in the context of a project I'm leading, called Yokozuna, which relies on distributed search.
> Here's the patch on Yokozuna: https://github.com/rzezeski/yokozuna/pull/26
> Here's a write-up I did on my findings: http://www.zinascii.com/2013/solr-distributed-search-and-the-stale-check.html
> I'm happy to answer any questions or make changes to the patch to make it acceptable.
