I'm using the multi interface but I still just want to determine the speed in a callback function. So it is just one single download.

I'm (already) trying to do it but I'm running into a problem again and again.
The callback is called very fast so the precision of seconds is not more enough.
I cannot determine the elapsed time that way. The result will be 0 all the time.

Maybe I could solve it with some functions the Operating System provides, but that is not a real solution for me.

Maybe I could slow down the process but wouldn't that affect the download speed? But I suppose I would slow down it unnecessarily.
