Weird... on a quick glance, I don't see anything in your config that would cause work to be done on a commit. I expected something like autowarming, or rebuilding a spellcheck index, etc. I assume this is happening even w/o any requests hitting the server? Could it be GC? You could use -verbose:gc or jconsole to check if this corresponds to a big GC (which could naturally hit on an index change). 5 minutes is really excessive though, and I wouldn't expect it on startup. If it's not GC, perhaps the next step is to get some stack traces during the spike (or use a profiler) to figure out where the time is being spent. And verify that the solrconfig.xml shown actually still matches the one you provided. -Yonik http://www.lucidimagination.com > Thanks, > John > > -- > John Williams > System Administrator > 37signals > > On Mar 8, 2010, at 4:44 PM, Yonik Seeley wrote: > >> Is this just autowarming? >> Check your autowarmCount parameters in solrconfig.xml >> >> -Yonik >> http://www.lucidimagination.com >> >> On Mon, Mar 8, 2010 at 5:37 PM, John Williams <j...@37signals.com> wrote: >>> Good afternoon. >>> >>> We have been experiencing an odd issue with one of our Solr nodes.
