True, but don't forget that all the files fetched have headers on them which can be compressed. With small images like pretty bullets, some backdrops, file icons etc those headers can make up a fair proportion of the data being received. > : With 15+ images and pages being fetched via my 28k I frequently see more than > : 7k/s which requires a serial speed of around 70k+ - OK its not 115200, but > : with a 57,6 you would be limited to 5k/s. > > sometimes when I'm at university with a very fast link, I don't get speeds > above 3k/s.

I can reliably get 3-4k/s from Acorns site via my 28K to a seperate ISP, and with the uni - god knows, the transfer speed doesn't appear for long enough for me to be able to read it :) cya -- Chris Audley, PartII Engineering student, mailto:chris@santaari.tcp.co.uk psychotic cyclist & Acorn RiscPC user http://www.tcp.co.uk/~santaari/chris/ Navaho WWW & Proxy Server home page: http://www.tcp.co.uk/~santaari/navaho/
