System: Dual P3 1Ghz on an Asus CUV4X-D
I'm using the 4.4 Stable source.

When I use the generic kernel, so not enabling SMP, the processor performs
as expected for a single CPU, as shown by benchmarks such as the dnetc rc5.

When I enable SMP, the processor(s?) go to pot and benchmark roughly at the
speed of a K6-200 (according to nbench). That's just through uncommenting
the 2 SMP lines but otherwise not touching anything else.

Any ideas why? Do I need to make any sysctl tweaks?

I'm relatively new to FreeBSD and this is my first time in using SMP.

Any suggestions gratefully received.

Jonathan Love
