loading lot of rules takes very long time

[Luigi Rizzo]

most likely, because you are not using "-n", the printing
code will use the nameserver to try and resolve addresses, and
if halfway through you are limiting/blocking access to the
nameserver you incur in timeouts.

To tell the truth i suspect you have a quite poorly designed
ruleset if you are adding individual rules and pipes for each
client. Almost surely you should make use of masks in pipes,
and address sets in rules, to reduce the size of your ruleset
to something manageable and efficient.
