The src.rpm was installed and then rpm -ba --clean XFree86.spec was used to build. ccache was not used. dual 933MHz P-III with 900KB ram in four sticks -- 71 minutes dual athlon 2800+ with 2GB ram (four 512KB sticks) -- 31 minutes Opteron 140 (1.4GHz) with 2GB ram (two 1GB sticks) -- 64 bit OS -- 43 minutes Opteron 140 (1.4GHz) with 2GB ram (two 1GB sticks) -- 32 bit OS -- 47 minutes The memory for AMD systems are all ECC REG memory. The Opteron 140 has a 128 bit path to memory (when 2 sticks are used) vice a 64 bit path on the Athlon64 ... even if the memory is the slower DDR2100. I chose the Opteron 140 as the cheapest 64 bit processor and was not expecting big performance. I have been very impressed (and surprised) with it so far. Note: during the builds, the runs on the Opteron had the cpu pegged while the P-III and dual athlon ran about 90% cpu. BTW, I believe that the Athlon64 3000+ has a 2.0GHz clock and 512KB L2 cache whereas the Opteron 140 has a 1.4GHz clock and 1MB L2 cache. -- Gene _______________________________________________ xfree86-list mailing list xfree86-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/xfree86-list IRC: #xfree86 on irc.redhat.com
