Sorry if this has been covered before. What are the preformance
implications of compiling a SMP kernel and running it on a UP machine?
Will that slow performance? The reason I ask is that I have a mixed bag
of SMP and UP servers. They all run the same hardware otherwise
(Adaptec scsi, 3com). Compiling one kernel and then distributing it
would make administration much easier.

What about a Hitchhikers guide to the proc file system FAQ?

Yes, no, maybe.
