>A microoptimization in the wrong place.
Caching and front end optimization are critically important, don't even try to say otherwise. And anyway, don't get so tripped up on that one comment. I was just using it as an example of not being execution bound (which nobody in the real world is...), you could easily replace web/proxy in that sentence with database and memcache.
Me? I'll never understand Asperger syndrome.
