FDM 3.9.3 network settings

Postby Guest » Sun Dec 15, 2013 1:22 pm

Hi, thanks for this great tool. Unfortunately I have problems with the bandwith restrictions, the limit doesn't work for me. Is this a bug or did I misunderstood the function?
Thanks
Jay

PC: Cannot add the screenshot, I configured
Downloads/Network/Connection speed: 1024 KB/s
Light Mode/Medium Mode/Heavy Mode Restriction of traffic: 100%
But the downloads run with the full bandwith.

Download speed is usually counted in bytes (B), bandwidth supplied by ISP is in bits (b), download is counted in binary units (Kilo binary a.k.a. kibi = 1024), bandwidth - in decimal ones (kilo = 1000).

But what is your bandwidth? 10 Mbps for bandwidth is almost the same as 1024 KB/s for file download speed. Useful data are transmitted in packets so you should count file data, packet frame data and control data into full bandwidth. Packet size is limited, and small files give bigger overhead than large files, but for simplicity you can count byte as 8 bits of data and at least 1 control bit transmitted. So 10 Mbps is 10 000 000 bits transmitted per second and 1024 KB/s is 1024*1024*9 = 9 437 184 bits transmitted per second.

Hi Andrzej, thanks for your quick and detailed response. With "full bandwith" I meant the highest download speed I normally see right in the bottom line of FDM ("total speed download") or in my other browsers, which is in my case approx. 1350 KB/s. So with my settings I expected a "total speed download" of approx. 1024 KB/s.
Thanks.

You should remember that 1024 KB/s is an average speed that FDM tries to keep for a longer time. But if you are already downloading a file with that speed and trying to start another download, FDM doesn't slow down existing connection immediately and you can see total speed greater than average. It may take about minute for FDM to slow down, so if you start more downloads in a minute, the total speed may be greater than average for longer time.

Well, the speed doesn't reduce till the end of the downloads.

New settings may work only for new downloads or after restarting FDM.

Do some tests as follows:
Close yor browsers, set really small speed for your connection (256 KB/s or less) in FDM and restart FDM. Now start a few new downloads, go to the main FDM window and watch the total download speed and the speed for every download separately.

If you still want to slow down more, you can also limit speed for every download separately - go to FDM menu Options | Settings | Downloads | New download, click "Advanced" button and on "Connection" tab find "Limit trafic" settings at the bottom of the dialog window.

Hi Andrzej, I changed the speed to 256 KB/s, restarted my computer (to be sure) and created a new download from microsoft.com. In a few seconds the speed went up to approx. 1350 KB/s and stayed there till the end of the download. The speed limit per file works but that doesn't really help because I would have to change the limit of all files every time the quantity of files changes to have the best speed below the limit.
Thanks
Jay

You are right, FDM currently ignores manual settings for connection speed in heavy usage mode. Manual settings work for medium and light mode now so if you really need it, you should change settings for medium mode and use it for downloads.

Hi Andrzej, the setting also doesn't work for medium and light mode.
