it still sucks! I've never seen such a sluggish ftp server.

OK It takes 4.138 secs. :( The logins seem to be fast. It's only when the users start to transfer files, then it takes forever.
Is there a way to make proftpd bypass the checks?

proftp can be (is by default?) configured to verify a valid IP before
allowing a log in.
If your reverse DNS is slow, then ftp logins and ssh connections can
take up to two minutes or so.
Microsoft based protocols don't do much IP based security validation,
based upon the OLD SMB protocols (ripped off from DEC and ISO standards).
Check your reverse DNS response times -- I bet they are whack.
You can use the host utility to test RDNS queries easily, or dig.
$ host 74.220.202.11
11.202.220.74.in-addr.arpa domain name pointer host11.hostmonster.com.
$ dig esourcehome.com

If these queries take more than a second or so, your are having DNS issues.
Good Luck!
