Okay folks,

I've been running the following settings for nearly a fortnight now, 
so here they are.

attach asy AUX: 0 ppp sl0 32767 576 19200 

tcp mss 536
tcp window 32000
tcp irtt 3000
tcp syndata on

ppp sl0 lcp local mru 576
ppp sl0 lcp remote mru 576

My newsfeed was down around 280-350cps, this can sometimes attain 
1000cps, more usually 800-1000.

I have had better than this by whacking the mru and mss way up high 
but that's *definately* not recommended in Tuning.Faq. While we're at 
it - anybody care to explain "tcp irrt" and "tcp syndata"?

Keep your old settings by commenting them out in case something goes 
badly wrong!!

In case anybody at Demon reads this the SRTT (from "socket") has been 
beween 1100 and 1800. There are definately a lot of resends during the 
initial NNTP connection upto the first article appearing. The 
impression I get is this ...

too many initial resends    -> resends carry on through newsfeed. They 
                               seem to reach a point of no return, and 
                               once this point is exceeded, the 
                               "resends against total" percentage 
                               throughout the newsfeed remains 
                               pretty constant. Lagged routing after 
                               dialup seems to play a part.
                               
not so many initial resends -> resends slowly fade through newsfeed. 
                               The less initial resends there are, the 
                               quicker it fades, sometimes down to 
                               zero.
