MTU MSS for increased thru put

What is the recommended MTU for WAN links, we have a 6M pipe from florida to Georgia and only seeing 300K-400K file transfers.

The VPN tunnel is showing no fragmentation with 1472MTU

Is this about the best I should expect?

Would the tunnel show pings not being fragmented and still fragmenting the packets?

Re: MTU MSS for increased thru put

What are your TCP window sizes? What is the RTT between the sites? You can get a satisfactory estimate of the RTT by using ping command.
