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...
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?
> Do you have any estimates on how much time is wasted, compared to the rest of the application? Profiling here is extremely important before making your program more complex. As I will often note, Reddit serves well over one billion page views a day, they use the SQLAlchemy Core to query their database, and the last time I looked at their code they make no attempt to optimize this process - they build expression trees on the fly and compile each time.
