Heya - So we just upgraded our Solr install to 1.4, and there's a great CPU drop and query response time drop. Good! But we're seeing the slowdown in the collection of statistics (stats.jsp) mentioned here:
http://www.mail-archive.com/solr-user@lucene.apache.org/msg30224.html to the tune of taking >100 seconds just to load it, I suspect that it does indeed (as mentioned in the thread above) that is has something to do with the fieldCache additions in 1.4. Loading stats.jsp on 1.3 with the same index was pretty much instantaneous. We (probably obviously) take things like avgTimePerRequest and avgRequestsPerSecond, cache hit ratios, evictions, etc. from stats.jsp and use it for both alerting (on thresholds) as well as tracking/trending/graphing/etc. Question: is there any plan to return this page to its previous fastness? Either by making optional the fieldCache stuff, or having an alternate method to get those metrics? Because at the moment, running 1.4 in production means essentially flying blind without those. :) cheers, j
