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.
