download manager shows unrealistic - wrong speeds

[kapetr]

The manager shows e.g. +- 350 kB/s but in real it is about +-100kB/s

I have see it many times by file sharing servers - e.g. ulozto.cz.
The downloads there with "dashed" speed, but download manager count the average speed out of reality. The reported speeds are shown unrealistic stable and +- 3x bigger then in reality.

I have compared it manually with

$ date;ifconfig eth0;sleep 60;ifconfig eth0;date

or with
$ sudo iptraf -d eth0

The wrong reported speeds and rest time is possible watch direct at download manager - the megabytes are added +- 3x slower then the wrong reported speed would transfer.

[sorry please my English]

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu and Firefox since that time.

Ubuntu 12.04 (precise) reached end-of-life on April 28, 2017.

Do you still see a problem related to the one that you reported using currently supported versions of Firefox and Ubuntu? Please let us know if you do otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
