I realize whether the data transmitted is raw, zipped, rar'd, 
yEnc'd or mimed doesn't matter, but I do not believe bitrate can 
exceed 56KB (if that) - and most of the others in the thread 
seem to feel the same way.

I HAVE noticed something interesting with MY 33.6 modem (laugh - 
it works great, and I'm in no hurry).

When dl'g *headers* from groups XNews *sometimes* - not always - 
shows bitrates approaching 25000 - fast as heck (well, for a 
dialup guy). Actual posts usually dl at about 3500. But most of 
the time the headers dl at about 4500-5000 - still faster than 
posts, but nothing like 25000.

I think this may have something to do with MRU - several headers 
probably fitting in one packet. (Am I using the right terms? The 
thing that used to be about half of 1500 and you had to modify 
settings for better performance, but Microsoft insisted on 1500 
and now the MRU my ISP uses is 1524 ...)

But if it IS the packets, why is the very rapid header download 
speed not standard but quite intermittent?
