It compiles faster than 4.0, so yes, gentoo people like it, it could save them one hour on a nice OpenOffice.org compile ;) When it comes to runtime, it's not much faster or better than 4.0, I think it's just about the same. The only package I've seen getting better performance out of gcc 4.1 is powerdns-recursor, but that's because the author of that software is working on GCC and knows exactly how to use new speed optimizations with gcc 4.1. He uses special compiler features when available to speedup the recursor by quite a few percents (over 20% for a piece of software that does only do DNS lookups and caching the results). _______________________________________________ arch mailing list [email protected] http://www.archlinux.org/mailman/listinfo/arch
