What exactly do you mean by that last statement? I would have said that
"very very slow" and "bandwidth looks good" mean almost opposite things.

Where are your LAN machines getting their DNS from?
What are you using to test, and finding things "very very slow"?
Do you see the same speed problem if you download something to the firewall as
downloading to an internal LAN machine?
Are you seeing lots of packets matching your DROP rules?
Have you tried a packet sniffer to see if there are unreplied packets on your
LAN or external link?

Antony.
