That'd be the critical distinction.

If you have a reproducible test case, ideally a single file, where GCC
3.1.x takes significantly longer (say, more than 10 or 20 percent) than
GCC 2.95.x, I'd consider this a regression.

Please submit such test cases via the GCC GNATS system and drop me a note;
while I probably won't be the one to fix the problem, I can (and will) try
to reproduce it and boost the priority of your PR!
