Subject Re: Does field collapsing (with facet) reduce performance?
Date Tue, 18 Jan 2011 00:27:18 GMT
There is always CPU and RAM involved for every nice component you use. Just 
how much the penalty is depends completely on your hardware, index and type of 
query. Under heavy load it numbers will change.

Since we don't know your situation and it's hard to predict without 
benchmarks, you should really do the tests yourself.
