Hey, My internet is provided via ADSL using PPPoE. When I take a look at ifconfig's output, I see that eth0 has an MTU of 1500, and ppp0 has an MTU of 1492. I don't _think_ that rp-pppoe (my pppoe util) is clamping the MSS. I am noticing some latency when there's a lot of bandwidth in use (but not >90%). What should I clamp, eth0/ppp0? How much? And what with, rp-pppoe, or tc/iproute2/etc ? I guess I don't really understand clamping MSS, can someone explain it in laymans terms? I have read the lartc-FAQ, and the only time I see clamping-MSS mentioned is section 15.7, which doesn't really explain why you'd do it. Apologies if M$ makes this email look squonky in any way.
