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 ?
