Andrew Muldowney commented on SOLR-2894:
----------------------------------------
Inital reports are that the newest version is a fair bit slower.
Caveats: We're still on 4.2 in production. So I've backported this to our 4.2
for testing. After going down that rabbit hole for a few days I've got the
.wars so I can better test tomorrow but a small sample of 400 production
queries on 166,343,278 documents had the following results
Old Patch
Average Query Time: 20.56ms
New Refactor
Average Query Time: 63.47ms
I'm using SolrMeter to run these at 200 qpm on a set of five slaves. Tomorrow
I'll give each version a much larger burn in, (the query file is 651mbs of
queries). I'm not sure these are statistically accurate but I wanted to share
what I'm seeing at the moment.
