Right - the purpose was not to micro-optimize.

The purpose was that someone suggested that a simple change might have a negative impact on everything (needlessly applying tr/// on all IDs). I didn't think it would matter, I had time to kill, and I was curious if the impact would be measurable or not.

Hmm, I must not have expressed myself clearly. It is not you, but your colleague who is guilty of (passive) micro-optimization, and focussing on a wrong thing. I agree that adding to the code and ending up with something that would appear to be faster, is indeed bizarre.	[reply]

I must not have expressed myself clearly. It is not you... I misunderstood you the same way. Can I suggest that the problem was that you said "you" when you meant "he"? Your original post had: Not only are you* micro-optimizing, but you're looking, IMO, at the wrong spot.* Hope this helps. -- Mark Dominus Perl Paraphernalia	[reply]

The original "you" was intended as plural. Really. :)	[reply]
