A little network and/or downloading question
I'm looking at a graph of my download speed, and at the moment I'm seeing a fairly constant speed of 250 kB/s, except for every 60 seconds or so, when the speed plunges and then pics up again over maybe 10 seconds. Would someone mind explaining to me why that is?

Note: this may be the problem, but it could be something else:Alan Bolte wrote:I'm looking at a graph of my download speed, and at the moment I'm seeing a fairly constant speed of 250 kB/s, except for every 60 seconds or so, when the speed plunges and then pics up again over maybe 10 seconds.

One thing that happens in TCP/IP is your receive window - which says how many packets can be in-flight at once, essentially. It starts small, climbs and when it gets too high the window gets cut in half - and starts growing again. Unfortunately, the current algorithms for window-size consideration are not particularly good for high-speed networks and can cause problems like this.
