Hoss Man commented on SOLR-4509:
--------------------------------
FWIW: It doesn't seem likely that this issue (SOLR-4509) is going to be
backported to 6x since it has some incompatible solrj level changes
(Configurer->Builder+SchemaProvider) but if I'm wrong and someone does decide
to try and backport it, please note that SOLR-9028 has already been backported
from master->6x and quite a few conflicts due to SOLR-4509 changes were
resolved there that might cause new conflicts here.
If SOLR-4509 is backported, it might be easiest to:
# revert the branch_6x changes related to SOLR-9028
# backport SOLR-4509
# rebackport the master changes for SOLR-9028
> Move to non deprecated HttpClient impl classes to remove stale connection
> check on every request and move connection lifecycle management towards the
> client.

> 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.
