Performance issues - slow packet filter

I noticed some download performance issues (HTTP and FTP) on a server that's in the DMZ segment. Putting all other testing aside, I'm focusing on just FTP traffic at the moment. What I find very strange is that a basic FTP packet filter rule is under performing an FTP proxy rule.

Downloads to an external client through the FTP proxy are about 1200 KB/s. Through the FTP packet filter I can only get 120 KB/s.

I've checked all bandwidth limiting settings that I can think of and everything appears to be configured correctly. Any ideas why this packet filter would be so slow?

    For FTP, the connection tracking portion of the proxy could be correcting some port/address translation issues which may account for the speeds.

    If you're using a packet filter, ensure that you're using the special FTP type, and not an Any packet filter, as this won't track the connections for FTP properly.
