Is the (hard) disk access very high?  If something has overflowed available 
memory and is causing a lot of paging, this would slow you down immensely 
because access times are now dependent not on RAM access times but disk 
access times.  Usual culprits are growing databases, indexes, mail spools 
or print spools.

Well, note his "in every other respect it appears to be working fast
and efficiently"... doesn't sound like a general slow-down of the
system, which a lot of paging would do.
