Is the default red hat 5.4 NFS server multithreaded?

[Ken Rossman]

Frankly, I don't see why any NFS server should NOT be
multithreaded.  Most operating systems running NFS server
processes end up running more than one of them, to handle
multiple parallel incoming requests.

And being that processor technology is moving in the direction of
multi-core multi-threaded processors as the norm (hence those
processors won't end up costing much more than simpler ones as
time goes on), it's just not worth worrying about to my mind...

Also, keep in mind that the average linux(unix) type system is
running lots of processes in parallel to support the general
operation of the machine, in addition to the specific set of
processes that comprise the intended service (e.g. NFS servers).

Hey everyone,
This is a pretty simple question but I can't seem to find the answer.
I'm looking to purchase a dedicated NFS server. Most of the vendors
are pushing quad/hex core processors. There's one model left that
still has a dual core. So far as I can tell, the default NFS server
isn't multithreaded, so even dual core is going to be overkill. The
server is going to be getting Log data copied to it N times a day,
where N is the number of times the files reach a certain size.

The only other thing the server will be doing is running a cron job
which deletes files that are more than 60 days old. Pretty simple,
right?
The only reason I can see justifying a quad core processor is if NFS
is multithreaded. Thoughts?
