Nice Article. I've a question regarding the kernrate tool though - I'd be glad if you could provide more details -

what bucket size have you typically found useful? Is there a rule of thumb on what bucket size to use? How do you know if we need to use a bigger/smaller number for bucket size?

Do you know of a tool like QSlice that will display activity for each CPU or that you can choose which CPU it will display. I have a server with 16 CPUs and no services appear to be having an impact yet several times an hour at random one CPU (usually CPU 10, 11 or 12) will almost flatline for up to a minute which sets off our monitoring software.

Why do you care about which CPU specifically is impacted? Qslice wont give the data, as you mentioned, but perfmon will give you the per processor utilization. This doesnt really help find out what is causing it though, does that matter in this case?

Very nice article - I like the tip about - unplugging the NIC - to check for local/remote sources for the problems.

In XP, probably you can also disable/enable the LAN in the Network Connections window.
