The download or upload speed of a file gradually slows down?

post #1 of 5
Thread Starter 

I've been wondering this for several years now - like I think even back in the days of dial-up.  Why does the download or upload speed sometimes get slower and slower the closer and closer it gets to finishing?

 

Now, I don't always see this.  I sometimes see the opposite.  However, it does happen often enough that I wonder why it happens - that is, if anyone knows.  I just wish that it should never do that.  Ever.  I wish that it would always keep a relatively constant speed, or even speed up like it sometimes does - but never slow down.  When it does slow down, it seems like it always waits until it's almost done!  It's like it knows when I'm in a hurry too.  lol

There's two things I can think of:

- I know Comcast has a speed boost that makes the file download fast for the first few seconds. That would obviously result in the download slow over time

-Speed estimates tend to be fairly inaccurate in many web browsers. They revise down to the speed you're really getting.

Additionally, after the file download is finished your PC may have to move it from a temp folder to the folder it's supposed to be in. This could cause some delay in a 5GB file. I think most browsers download directly to the directory these days though.

Oh, I was kidding about the 5 GB file.  I've been noticing this since the days of dial-up.  So maybe your second point applies that the speed estimates are fairly inaccurate in many web browsers.  I honestly hadn't even considered that.

 

I do remember the days of IE downloading to a temporary directory first because I remember the end of the download would mention copying the file over.
