Thank you Ben.  Can you elaborate some more on the above point?  Are you 
referring to the OS's working set or the Cassandra caches?  Why exactly 
do I need to ensure this?

I am also wondering if there is any reason I should segregate my 
frequently write/read smallish data set (such as usage statistics) from 
my bulk mostly read-only data set (static content) into separate CFs if 
the schema allows it.  Would this be of any benefit?
