PPC speed

Hello, I did some benchmarks on a 2.6Ghz Xeon and a Pegasos2-PPC using ab2 (apache bench) and sysbench (mysql) on SUSE Linux and Gentoo. On the Xeon workstation there was not much difference, SUSE and Gentoo were head to head, Gentoo usually (but not always) 5-10% faster. The real supprise came the PPC platform: Gentoo was serving static webpages about 2x faster, and sysbench was about 1.6-1.8 faster on Gentoo. Is there any optimalisation in the SUSE packages? Gentoo packages were compiled with the following CFLAGS in /etc/make.conf (this Gentoo was preinstalled on my ODW, I just refreshed sources and rebuilt it without changing settings): CFLAGS="-O2 -mtune=G4 -maltivec -mabi=altivec -fno-strict-aliasing -pipe" Bye, Peter
