When downloading from an arbitrary site, your observed speed will depend on the slowest link in the path of hops between that site and your system, and that is generally not known in advance. With cable, your bandwidth is shared with a (hopefully) small group of neighboring subscribers, and if all your neighboring subscribers happen to be downloading at the same time, your performance (and theirs) will suffer. The only practical thing you can do that I know of is to shoot your neighbors, but that is going to extremes. I can generally count on download speeds of 125 k bytes per second, and have seen as high as 250 k bytes per second, and as low as 13 k bytes per second. The last figure was due to limited upload bandwidth at the originating site. My upload speeds when doing an FTP to my ISP runs from 15 to 25 k bytes per second. I cannot account for the variation by anything over which I have control. Chuck -- The Moon is Waning Gibbous (92% of Full) My home page is at http://www.mhcable.com/~chuckh
