regarding Solr Caches

Hi,
This question might have been asked on the solr user mailing list earlier.
Solr has four different types of Cache DocumentCache, QueryResultCache,
FieldValueCache and FilterQueryCache.

Are these Caches memory mapped or they reside in the JVM heap?
Which Caches have the maximum impact on the query latency?
Any recommendations around Cache size settings or any documentation would
be very helpful.

I also would like to know if there is any document which provides
guidelines on performing Capacity planning for a Solr cluster.

Regards
Suresh
