premature optimisation would be writing something in C(++) when it
isn't the bottleneck.

the database is currently the bottleneck and i'm pretty sure they
already wrote that in C :-)

what was %age gain? i mean, if its a 10ms improvement on a 500ms call
then it might not be such a big deal. if its a 10ms gain on an 11ms
call that would be fantastic.

don't forget that the rails port also handles user management,
friends, messages, diaries, gps points, etc... it would be better to
say you have implemented part of 'old' API 0.5.
