It is trying to fetch the current settings to pre-fill in the form.  If it
fails, it may wait for a timeout period.  This would be the slowness
you see.

> 3) The entire page takes a couple of minutes to load

Probably the same as #2 above, but influenced by something like page
compression or browser quirks.

You mean, I hope, for that one user?

My guess is that the ftp connection to retrive the current values is failing,
and your ftp server connection takes a while to timeout, causing the delay
you see.  You can verify this by not having it check the current settings,
and see if the problem goes away.

You can do this by disabling "isEnabledForwarding()" in the ftp class file.
