Running -Stable make world with recent Intel and AMD hardware yielded some interesting results. One machine: CPU: AMD Athlon(tm) 64 Processor 3200+ (2010.31-MHz 686-class CPU) Origin =3D "AuthenticAMD" Id =3D 0x20ff0 Stepping =3D 0 Other machine: CPU: Intel(R) Pentium(R) 4 CPU 3.60GHz (3600.12-MHz 686-class CPU) Origin =3D "GenuineIntel" Id =3D 0xf34 Stepping =3D 4 The Intel machine had hyperthreading disabled in the bios. kernel config for both machines was GENERIC Running 'make world' several times on FreeBSD 6.0-STABLE from 11-26-05 a couple of representative timings were: AMD Athlon 64 45:42 45:19 Intel P4 55:22 54:57 Are there any optimizations for the P4 which might be added to the GENERIC kernel config to improve the performance ? -kim -- w8hdkim err gmail.com
