Subject: [LARTC] TCP MSS clampage
Date: Thu, 28 Feb 2002 16:02:54 +0000	[thread overview]
Message-ID: <marc-lartc-101491222506911@msgid-missing> (raw)

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.

Thanks,

Tim Carr
