: A can tell you a little bit about ours... on one CNET faceted browsing : implementation using Solr, the number of facets to check per request : average somewhere between 100 and 200 (the total number of unique : facets is much larger though). The median request time is 3ms (and I : don't think the majority of that time is calculating set : intersections).
I've also posted some other numbers for a differnet CNET page which doesn't seem very "faceted" but actually does many more DocSet intersections to rank categories (1500-2000 per request), and does a lot more complicated main search queries (really big nested Boolean/DisjunctionMax/Phrase queries). The average request time there was 30ms ... but more importantly (to me and the people i work with anyway) the 99.9th percentile was only 456ms http://wiki.apache.org/solr/SolrPerformanceData (note: this was before the OpenBitSet changes Yonik just commited) -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
