FileZilla Forums

How to reproduce:
- set a transfer limit (say 1500 KiB/s)
- download a big file (say 5 GB)
- after some time, reduce the transfer limit (say to 400 KiB/s)
(even minutes later, the speed is still displayed wrong)
- a few minutes later, increase the limit again (say 1500 KiB/s)
(5 minutes later, while the file is being transferred with 1500 KiB/s, FileZilla displays it as "(1,1 MiB/s)" on the right side of the progress bar)

How about using only the last 3 seconds or so to calculate the current transfer speed that's displayed?

It's not a bug, the speed displayed is an average over the complete transfer period up to that point.

You can select to display momentary transfer speed instead in the global settings.

Oh, I had totally overlooked that option! Will try that, thanks.
