Thanks, tcpdump is cool :)

I can see use of my isp dns etc. Very oddly things have speeded up
again at some point this afternoon ? Perhaps, its not 'my fault' and the
isp are up to something ?

Anyway, its nice and snappy again so sorry for the noise (I learnt  
though - Tnx!)

Any tips for fine tuning tcp over adsl ?

BTW - I compiled ipv6 out of my kernel - did I do bad ?
BTW2 - Is it worth configuring Bind for local use on a single box ?
Even from an educational viewpoint ?
