I'm not sure why profiling MySQL would help. HyperDB doesn't make 
existing queries faster by itself, it just allows you to distribute them 
across many hosts.

A better thing to benchmark would be front-end performance, which is 
fairly easy with something like siege or ab. Crank it at your front page 
and watch the loads on your web and db box, see which maxes out first, 
and then you know where to expand.
