I am all to see it included in the next Gentoo as default. The compilation time is indeed slower than GCC 2.95.X, because it does things that are more complex (hey, they have fixed their previously half-baked C++ support) and because it has not been optimized yet. However, the trade off is acceptable, because you got Konqueror or other (especially) C++ applications to run TIMES faster, *especially* when optimized for PPRO and above (i686). GCC 3.x does not generate as good and fast code as the Intel compiler ("Proton") does, but it certainly beats GCC 2.95.x as much Proton beats GCC 3.x. ;-D So, regarding your benchmarks Spider. There is something wrong, definately. And I think our gentoo kernel heads around here should take a close look at it. Sure, GCC 3.X *is* slower on compilation time, however, your tests show a very disturbing fact: Under some circumstances, your CPU seems to spend unreasonable amount of time not doing anything. This could be an indication of a bigger issue, possibly a configuration or a hardware issue. There might be an issue going on with the cache or the filesystem or even the loader. How much memory the PC you used has and what kind of drive and filesystem did you use? (I hope that all this is not a side effect of one of the Gentoo kernel patches...) On a completely different issue, I just emerged Netscape 4.x. Netscape's fonts when loading any page are extremely small while Opera's fonts are ugly as nothing else on this planet. I think some Xft configuration is not done properly... Also, when one emerges XFCE, XFCE does not load its window manager, because the xfce little script on /etc/X11/Sessions/ asks for the 'xfce' binary instead of the standard 'startxfce'. As for the KDM problem that someone also mentioned in this list, I have the same problem. The user "eugenia" (part of the 'wheel' and 'audio' groups) cannot load KDM (it just doesn't load anything, with no errors displayed), while everything runs fine as a root. Any ideas? (standard X with twm works fine for user 'eugenia' over here) Best Regards, Eugenia ----------------- Editor-in-Chief at http://www.OSNews.com Email: eugenia@osnews.com - ICQ: 6070904 Home page at http://www.eugenia.co.uk . _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx
