Hi,I've just completed some formal timings of one of my Perl/XS/C modules running under Perl 5.6 and Perl 5.8. Both modules were built with gcc version 3.4.2 (mingw-special) against Activestate on win32.
Perl 5.6.1 (build 638 ActiveState) = 94676 iterations per second. Perl 5.8.7 (build 813 ActiveState) = 68677 iterations per second. Quite a difference! No idea why... Cheers, jez.
