I consider this kind of stuff the compilers job -- so if I write or 
maintain code that is slow, I know there is probably something I can do 
about it w/o having to drop into assembly.

Personally I've spent a huge amount of time tuning code and I can't tell 
you the positive effect that has on end-users. IMHO bad performance is 
often the "forgotten bug" (that's not to say the budget should be busted 
on that "last 20%" either though).
