Do multiple downloads affect over all performance?

Asked by dreamwolf (3142 points ) September 11th, 2011

So I want to download multiple 7gb’s worth of downloading. Will it drastically change the time if I download (2) 7gb’s worth of stuff compared to (1) download of 7gb’s?

Your downloading twice as much. Downloading multiple things will use up more sppeed and slow eachother down, even downloading a 350 mb thing, they will take away from eachother.

@XOIIO Will it drastically change the speed? Or would downloading one at a time be faster than both at the same time. Or would both options occur with the same download end time. Duh

It depends. The download speed is limited by how quickly the server is sending you the file. Often servers limit this so as not to blow all their resources on one job. Therefore if a download isn’t using all your bandwidth you can download two or maybe three files with out losing anything. For example iTunes can download three files in about the same time as one file.

@Lightlyseared That’s what I’m talking about!

The other limiting factor is your ISP. At times when the ISP has most traffic things start to slow down. For web pages this often doesn’t matter (if it takes a tenth of a second longer would you notice?) but for large files it starts to add up. ISP’s often start to manage traffic at busier times so video streaming will get priority over other things (and things like bit torrent is often throttled badly) do choosing when you download makes a big difference. I find between 3am and midday is probably the best time.

@dreamwolf It doesnt matter how fast the original download speed is, for every new thing tyou add expect it to drop by half. You also increase the risk of resetting the connection and loosing your download.
