I have a fairly new install of 6.4, done over the 'net, on this old

Performance was *rather* sluggish so I tried to ascertain if both
processors were running:
# dmesg | grep cpu
cpu0 on motherboard
Q1. Is there a better way to establish how many processors are running?
Q2. Do I need to specify, say in rc.conf, that I *want* SMP to be enabled?
Best regards,
top should display a C column with a number that represents which cpu
the process is running on. IIRC, ACPI must be enabled for SMP to work,
and ACPI didn't work on my MB until 7.0. We have different boards, but
upgrading to 7.2 would probably be a good idea if possibile in your
situation as both 7.0 and 7.1 saw significant performance increases in
certain areas.
also "sysctl -a |grep kern.smp.cpus" should return your cpu # for
7.x(not sure on 6 anymore).
