Funny story: I have worse performance with g++-4.3 (20% as well) I probably overoptimized for g++-4.2 or something :)
FYI g++4.4 is about to be released. it is already in experimental debian repository Lukasz 2009/4/21 Adrian Grajdeanu <adria...@cox.net>: > Just to add my 2c for the performance freaks.
