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?
