It sounds quite obvious to upgrade the java environment to go on with that.
We are updating our index almost every second and so over time it counts up a lot of segment files (up to 32 in our case). So optimizing was always a good idea in the SOLR 3.X world. We regocnized that in SOLR 4.4.0 it does not hit performance that bad if the index is not optimized for a period of time. But we like to avoid getting to much segments at once.
Today I will run one more checkIndex run against the now turned off SOLR instance.
Maybe there will be some enlightment then. Bet regards Ralf Matulat Am 13.01.14 21:15, schrieb Michael McCandless:
I have trouble understanding J9's version strings ... but, is it really from 2008? You could be hitting a JVM bug; can you test upgrading? I don't have much experience with Solr faceting on optimized vs unoptimized indices; maybe someone else can answer your question. Lucene's facet module (not yet exposed through Solr) performance shouldn't change much for optimized vs unoptimized indices. Mike McCandless http://blog.mikemccandless.com
