What version of CUPS are you using?

We have a few customers with 10,000+ printers on a single server.
In your case, there aren't too many things to tune, but the main
issue is which version of CUPS you have - newer versions of CUPS
scale much better.

We don't generally recommend managing printers via the web
interface with that many printers, BTW... :)
