All this on AMD64, Linux2.6, gcc3.3. FWIW, my AMD64, linux 2.6, gcc 4.0 machine reports 29.0-29.5 usec for 2.5, 30.0-31.0 for 2.4 and 30.5-31.5 for 2.3, using the code you attached. In other words, 2.5 is definately not slower here. At least, not if I use the same compile options for 2.5 as for 2.4... ;-)
I checked, both Python versions were compiled using these options (and the same compiler):
Compiler options
OPT= -DNDEBUG -g -O3 -Wall -Wstrict-prototypes BASECFLAGS= -fno-strict-aliasing
Perhaps it's a new feature in gcc 4.0 that makes the slow-down I see turn into a speedup :-)
