Once you start getting into the realm of 10 or so nodes, I'd expect select to start slowing down a bit.
We also resolved a performance issue with select (http://www.couchbase.com/issues/browse/CCBC-407) which would have also caused a slowdown. I'd ask that you try 2.3.1 and see how that works for you.
