Does anyone know a firewall software which doesn't slow down the comp when torrenting?

My stupid McAffee firewall will cause my comp to lag if I run BitComet overnight. I guess it cannot differentiate between connection to peers from unauthorized access stuff. Is Zone Alarm any good? I would also like to know which firewall software uses the least amount of resources

Well, I would like to know one which uses less resources unlike norton's internet security suite thing which hogs up way too much resources.

McAfee Firewall does not have a setting for that. I'm using the older version btw because the newer one offers less customization similar to Vista like products which are meant to be more "user-friendly"

Reason being is that it there are tons of connections going throgh BC and the firewall will slow down the PC by scanning all those incoming connections eventhough the permission is set to Full Access
