Solr is now up and running on our production environment and working great. However it is taking up a lot of extra CPU and memory (CPU usage has doubled and memory is swapping). Is there any documentation on performance tuning? There seems to be a lot of useful info in the server output but I don't understand it.
Swapping if it's constant isn't good... How much memory does this box have, and what is the heap size of the JVM? Are there other things running on this box? Solr does warming of caches by default to make complex queries that hit a new snapshot of the index fast. This takes up CPU in bursts, but is normally nothing to worry about unless you have other apps running on the same box that need CPU. Because of this warming, CPU usage of a Solr collection isn't directly related to query traffic at all times. -Yonik
