Hi, I run several buildworld's on both, an Alpha EV56 and a Intel PII. I'm wondering that the Pentium beats the Alpha. Both systems have INVARIANTS* and WITNESS* disabled. Furthermore, no special tweakups - nearly "out of the box" configured. Alpha EV45, 600MHz, single CPU 768MB RAM UW-SCSI SEAGATE ST34573W 6244 running: 5.2.1-RC2 (15th Feb 2004) building: 5.2.1-RC2 (15th Feb 2004) /usr/src ufs, /usr/obj ufs make buildworld 19808.17 real 17126.29 user 1965.42 sys make -j2 buildworld 20085.05 real 17314.00 user 2139.92 sys make -j3 buildworld 20182.12 real 17467.14 user 2175.41 sys ######################################################################## Intel PII, 333MHz, single CPU 256MB RAM UDMA33 WDC AC26400R running: 5.2-CURRENT (20th Feb 2004) building: 5.2.1-RC2 (15th Feb 2004) /usr/src ufs, /usr/obj ufs make buildworld 16916.70 real 14185.83 user 2028.82 sys make -j2 buildworld 16991.71 real 14445.95 user 2201.29 sys make -j3 buildworld 17042.71 real 14532.71 user 2235.48 sys make -j4 buildworld 17171.15 real 14583.99 user 2242.81 sys And I don't think CURRENT is that "faster" than 5.2.1. Why does (my) alpha performs so bad? Some ideas? Is that behaviour common for FreeBSD/alpha or did I missed something in my consideration? -- Oliver Lehmann http://www.pofo.de/ http://wishlist.ans-netz.de/
