Transfer speed limit

Hi.

It would be great if you implemented speed limit options when using cloud/external sites to sync with.

Best regards, and thank you for a great program.

Bump. Also would like to know if this is possible for the same reason.

I second the wish for a throughput limit.

Would be great. I am on WiFi for my work-laptop so bandwidth is limited and now FFS is taking up all bandwidth and I can't work/browse the internet anymore.

For other tools like FFS I use NetLimiter where you limit the speed for each application/process. But the way FFS is implemented this is not possible.

Well I found this expert setting called RunWithBackgroundPriority see https://freefilesync.org/manual.php?topic=expert-settings

Just sync and wait when files are copied... this will be at full speed.
Then do simultaneously a https://www.speedtest.net
and notice a drop in FFS speed but (almost) full speed at speedtest.
Works great.

Thank you very much. Just changed the RunWithBackgroundPriority section to:

<RunWithBackgroundPriority Enabled="true"/>

Saving the GlobalSettings.xml file in the following location:

%AppData%\FreeFileSync

I appreciate your help!

Well there is still 1 disadvantage... other computers will still suffer bad wifi speeds because FFS "won't notice them". So speed limit would still be usefull.

All with you there. This happens to my home-network.

This is do not work in 11.5

Posts: 35 · kalich 8 Jan 2021, 10:05

Version 11.4 work GREAT

Posts: 10 · jantje 8 Jan 2021, 11:23

v11.5 works also in my experience... Be sure to first close FFS, then update the RunWithBackgroundPriority in GlobalSettings.xml, save it, then start FFS.

I did that. I even restarted the computer. But the problem reappeared for me on 11.4.

Couldn't the problem be that I'm using the Portable version?

Posts: 35 · kalich 27 Jan 2021, 08:31

The application is still overloading the network. Restriction via <RunWithBackgroundPriority Enabled = "true" /> does not work!

That will not change. If you are doing nothing on your PC, FFS will take all available bandwidth of your PC. If that happens to be the max. bandwidth of your network other clients will notice this in their limited speed.
If you are doing some browsing or downloading then FFS will be running on a lower speed. At least during my testing.

To prevent the situation you are experiencing we still need a speedlimiter option in FFS. I couldn't get NetLimiter to work.That's why my post "by jantje • 04 Jan 2021, 09:40". Maybe there are other bandwidth control applications that will work. If so share here.

Out of curiosity, why Netlimiter don't work with FFS for you?

Posts: 35 · kalich 27 Jan 2021, 21:15

I would just appreciate the ability to set the maximum transfer rate.

Posts: 292 · Gianni1962 27 Jan 2021, 23:54

In my experience NetLimiter does this but it is not free.

Posts: 10 · jantje 28 Jan 2021, 15:46

@Gianni1962 Please share how you accomplish this.
NetLimiter is a great tool and does work for me with other programs.

Posts: 292 · Gianni1962 28 Jan 2021, 17:06

If you already use it, you should already know how to set it up.
It is not an easy task to explain in text the abc of NetLimiter.

First try this NetLimiter guide: https://www.netlimiter.com/docs/basic-concepts/limits

I'd really like to have this be a built-in feature of FFS, as I'd like to be able to recommend that feature to friends/family who are less tech-savvy, and could really use it myself for a sync I'm using now.

I often use FFS over Remote Desktop rather than setting up a VPN.

Everything else then becomes a snails pace where FFS takes over the bandwith. Is there a application that can throttle the IO for a specified process, that's free and hopefully open sourced?

I do feel it's a shame this feature is missing.

I use NETSPEED LIMITER 4.0 and it's great I gave it 50kb U/S and let it run all day, my files are all kept safe.

Glad i searched that is a nice expert option but i still feel like having something like Filezilla's transfer speed limits download/upload limit thing or potentially a thing which lets you set speed limits based on time of day would be handy so i could let it trickle during work hours but then while sleeping go full speed without having to set a bunch of crons to start stop and not overlap if not done.

Example:

Btw a donation edition person here.

Thanks in advance for the amazing app and tool

Maybe there are some helpful ideas here to limit the transfer/upload speed, but I prefer the straightforward ways to do this task and for example :
- Duplicati , There is a speed control in the GUI version (it was a bug in 2.0.5.1 Beta, fixed in next Beta and in 2.0.6.0)

- Gs Richcopy360 , it has an effective feature which can control the speed while uploading / transferring
