Does Dropbox limit the upload speed? Very Slow uploads!

[Soonjas]

I am experiencing the super slow upload speed via Dropbox desktop App ( v 120.4.4598 ) and I am running Windows 7. It used to be good and only recently noticed super slow upload speed. Funny thing is, upload via chrome browser works and utilizes my bandwidth to the max which is great. I have tried reinstalling the app, playing around with settings, rebooting router and modem, speed tests, tried that fix by merk. Also have tried installing Dropbox onto a laptop (win7) and get the same upload speed around 250KB/s. It seems like there is hard limit on the upload speed set by Dropbox.

I have wasted too much time on this. It is not my internet, as upload speeds are great to Google Drive and other speedtests, even the dropbox browser upload is fast.

Conclusion is the desktop app upload is slow. Definitely something wrong with the desktop app. So tempted to try the Filezilla Pro option, have to pay though =( 

Please fix this Dropbox!

Hi @Soonjas, thanks for your post!

Indeed, syncing your files can take time if you have many files or large files, however, the Dropbox servers do not set caps on the upload or download speeds from the Dropbox desktop client. 

Have you tried the steps in this article to see if they help with your syncing speed?

Let me know how it goes.

[Soonjas]

Yes I have tried those but it does not fix the issue.

I tried installing dropbox on another two laptops(windows 7) and it has the same issues.

I then installed dropbox on a different laptop(windows 10) and THERE IS NO ISSUE.

So the problem is with Dropbox app and Windows 7. There seems to be a hard cap on the upload speed. Can this be please investigated by dev team?

Can you check one thing for me? This particular version of the Windows OS (Windows 7) needs the security update KB3033929 for the Dropbox desktop app to work properly. 

Is it possible that you don't have this update? It might explain this situation. 

Let me know what you find!

Hi Hannah,

It's already installed on my computer, and others. They are fully up to date with windows updates........

THanks

Hi @Soonjas, in general, there is no limit to the upload speed, regardless of the OS, if you have the limit removed in the desktop app preferences. 

As you're experiencing this, there is a possibility that a proxy, VPN, firewall, or security software issues on those Windows 7 devices could be restricting traffic to the following Dropbox domains.

[Soonjas]

That can't be true. As I said, I can upload fine via Dropbox browser( Chrome browser). when I upload via the Dropbox app, it appears to have a hard limit on the upload rate.

The browser is a separate app when compared to the desktop app, so different services on the computer might not affect the browser.

Try to disable any security apps or antivirus programs to see if they help with the desktop app upload speed.

[Soonjas]

I don't have any antivirus software running or security apps on all three of my Windows 7 devices. 

It was working fine, until the recent updates to the Dropbox app...........There are others also experiencing this same issue
