rendrag Posted February 15, 2008 Share Posted February 15, 2008 it's nearly impossible to get 56kbps while surfing. 56kbps = 7KB/s, so you should see throughput at less than 7KB/s on your dial-up connection.for gprs, at 460kbps, you should be getting 57KB/s, so it's possible they're limiting your download speednote that kilobits per second (kbps) does not equal kilobytes (KB/s). Take kilobits and divide by 8 and you'll get kilobytes. Link to comment Share on other sites More sharing options...
D_block Posted February 15, 2008 Author Share Posted February 15, 2008 so are you saying when downloading i should be able to get about 57kbps max on my 460kbps connec Link to comment Share on other sites More sharing options...
bober Posted February 15, 2008 Share Posted February 15, 2008 rule of thumb:80% of advertised rate.maximum. Link to comment Share on other sites More sharing options...
rendrag Posted February 15, 2008 Share Posted February 15, 2008 (edited) so are you saying when downloading i should be able to get about 57kbps max on my 460kbps connecfor gprs, at 460kbps, you should be getting 57KB/snote that kilobits per second (kbps) does not equal kilobytes (KB/s). Take kilobits and divide by 8 and you'll get kilobytes.kbps <> KB/s :: The reason I bring that up is when you look at a download progress bar, they show the speed in KB/s which is not kbps. This way you have a more accurate representation.if you use the 80% rule, that equates to 46KB/s on a 460kbps connection. So they might be limiting http or ftp traffic Edited February 15, 2008 by rendrag Link to comment Share on other sites More sharing options...
cluberti Posted February 15, 2008 Share Posted February 15, 2008 The reason for this, in a nutshell, is that TCP/IP has some overhead on the connection - if you've ever used other protocols in the past (like IPX, for instance), especially on non-ethernet or dialup (say, token ring ) you see almost 100% saturation. TCP/IP gets you roughly 80% util, and less on an ethernet lan (although good 100/1000Mbit switches can offset that a bit). Link to comment Share on other sites More sharing options...
