How much NMIs per second?

Hi,
I did not follow discussion about NMI-deadlock-patch on linux-kernel
very closely, but I have one small question: How much NMIs there should be
per second? My system gets 100 timer ints (50/s per CPU) and 100 NMIs
delivered to both CPUs (i.e. 200/s total). Is it correct? (I do not know
what happened to two NMIs on CPU0, after reboot counters are in-sync
(I think that it was caused by vmware - I tried it run twice and
I twice got internal bug - probably vmmon is not happy from receiving
periodic NMI - it could be these two)):

CPU0 CPU1
0: 25173 24603 IO-APIC-edge timer
1: 1489 1389 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
8: 2 0 IO-APIC-edge rtc
12: 5200 4410 IO-APIC-edge PS/2 Mouse
13: 1 0 XT-PIC fpu
14: 2864 2622 IO-APIC-edge ide0
16: 17999 17912 IO-APIC-level bttv
17: 11793 12172 IO-APIC-level bttv
18: 2484 2455 IO-APIC-level ESS Solo-1
19: 3447 3336 IO-APIC-level eth0
NMI: 49707 49709
LOC: 49691 49691
ERR: 0

Machine is Soltek 68A, 2x PIII/450, 256MB RAM, USB interrupt still
routed wrong, 18GB EIDE.
