Hi all,
I'm having trouble getting my Solr setup to get consistent performance. Average
select latency is great, but 95% is dismal (10x average). It's probably
something slightly misconfigured. I’ve seen it have nice, low variance
latencies for a few hours here and there, but can’t figure out what’s different
during those times.
* I’m running 4.1.0 using SolrCloud. 3 replicas of 1 shard on 3 EC2 boxes
(8proc, 30GB RAM, SSDs). Load peaks around 30 selects per second and about 150
updates per second.
* The index has about 11GB of data in 14M docs, the other 10MB of data in 3K
docs. Stays around 30 segments.
* Soft commits after 10 seconds, hard commits after 120 seconds. Though,
turning off the update traffic doesn’t seem to have any affect on the select
latencies.
* I think GC latency is low. Running 3GB heaps with 1G new size. GC time is
around 3ms per second.
Here’s a typical select query:
fl=*,sortScore:textScore&sort=textScore desc&start=0&q=text:(("soccer" OR "MLS"
OR "premier league" OR "FIFA" OR "world cup") OR ("sorority" OR "fraternity" OR
"greek life" OR "dorm" OR "campus"))&wt=json&fq=startTime:[1392656400000 TO
1392717540000]&fq={!frange l=2 u=3}timeflag(startTime)&fq={!frange
l=1392656400000 u=1392695940000
cache=false}timefix(startTime,-21600000)&fq=privacy:OPEN&defType=edismax&rows=131
Anyone have any suggestions on where to look next? Or, if you know someone in
the bay area that would consult for an hour or two and help me track it down,
that’d be great too.
Thanks!
