Subject Is caching worth it when my whole index is in RAM?
Date Mon, 31 Aug 2009 14:55:13 GMT
If I've got my entire 20G 4MM document index in RAM (on a ramdisk), do I
have a need for the document cache?  Or should I set it to 0 items, because
pulling field values from an index in RAM is so fast that the document cache
would be a duplication of effort?

Are there any other caches that I should turn off if I can get my entire
index in RAM?  Filter cache, query results cache, etc?
