I feel rather underwhelmed by the performance improvement touted by adequate records. Perhaps someone from the rails community can do something like this: http://techspot.zzzeek.org/2010/12/12/a-tale-of-three-profil...

100% speedup is underwhelming?

100% speedup to certain queries, not all queries. How many queries it covers will depend on the app; as well, of course, how much of app wall time is taken up on queries.

I too am curious how noticeable an improvement this will be in most apps. Is it a micro-optimization that won't be noticed much, or is it actually going to make a difference for real apps?
