1) Define "speed" ? how are you measuring? where are you measuring? are you measuring averages? over what sample size? 2) define "particular query" ? what types of queries? what types of params are in the request? what do the results look like? 3) Define "any changes" ? new docs? deleted docs? updated docs? restarted server? restarted solr? increased query load? -Hoss http://www.lucidworks.com/
