These were my "establish a beachhead" approach to figuring out where to spend my optimizing time (e.g. WTF is taking the most time in the 1st place, eh? Anyone else have any luck with either of these (or come up with another) profiling tool to start zeroing in on where the cycles are being spent? --Garrick Well, Benchmark was a waste of time and RubyProf seems to spin into infinity for me.
