Ouch! The big question is: are you actually doing anything else with
that server? If Rails has the machine all to itself, and you don't
have enough traffic that someone else is probably waiting for a reply,
you may be OK as-is.

Otherwise, a number of other approaches come to mind. As you
mentioned, you could put it on another machine. You could also see if
you could "nice down" that process, i.e., use the "nice" utility (or
some such programming) to set the priority of the PDF-making process
so that others can have a better share.
