I assume you're asking if the large number of "deny from" directives is
going to have an effect on speed. The answer is probably not. In order to
deny from specific hostnames, apache must first resolve the visitor's IP
address into a hostname. It's this resolving which will slow things down,
but the chances are apache does this anyway. After the IP's been resolved
(and it will be resolved only once), it probably doesn't make a lot of
difference how many domains you check it against (maybe adding fractions of
a milliseconds on to each query).<!-- ~MESSAGE_AFTER~ -->
