...crappy reflexes...

For those of us who are happy when something actually compiles, how do you actually determine this? My kung-fu is not powerful, but I've written a basic compiler, and as I understand it the optimizations are the really hard bit. Presumably this is where you notice it, with the new compiler creating poor performance?

Well, one thing you do is collect metrics about code size and page-load time that leave you hanging on a 10ms or 10KB change like it was the three-hour IMAX-filmed final episode of "Survivor: Friends". And then you have people like bryner who spend a lot of time thinking about compiler output and how to trick gcc into producing code that is fast and small. I can barely read x86 assembly, so I avoid that sort of duty.
