Theoretically there should be no limit. Depending on your load,
however, the process will likely chew up more CPU time as your
lists get bigger.

splay trees are used for only certain ACL entries:

        src/dst IP addresses/networks
        src/dst domain names

large lists of these ACL types should scale pretty well. A large
URL regular-expression list does not use splay trees and probably
performs very poorly.
