Upload app sync speed is very slow on macOS.

Hey TWISTY, I'd be more than happy to help! 

Are you certain that you have no other software that could be monitoring the Dropbox folder or app?

Have you contacted your ISP for further assistance on this matter?

Also, how many files do you have inside your Dropbox folder at the moment? You should be able to check its Properties, if you need to find out more. 

Let me know how it goes.

Thanks for the reply.

No new software has been installed in the last 6 months or so.

Have you contacted your ISP for further assistance on this matter?

Yes, they said if it isn't affecting other apps then contact dropbox. I checked by uploading a 500MB file to Google Drive via browser which took 3 minutes.
I uploaded the same file to dropbox via browser which also took about 3 minutes.
This same file would take hours on dropbox via desktop app.

Also, how many files do you have inside your Dropbox folder at the moment? You should be able to check its Properties, if you need to find out more. 

On my desktop there are 235,535 items, most of those are "online only".
I do use selective sync so there is a lot more within dropbox that I do not need access to.

Thanks for the heads up TWISTY!

Definitely keep an eye on it, and let me know how it turns out. 

Seems to be working fine now. For reference, the below is what fixed it.
1. logged out of dropbox

2. uninstalled drobox

3. reinstalled dropbox
4. logged back in

The slow syncing issue came back. But once again doing the following solved it. Hopefully it doesn't happen every 2 months....

1. logged out of dropbox on desktop app (preferences > accounts > sign out)
2. uninstalled drobox
3. reinstalled dropbox
4. logged back in

I've been having this problem intermittently for years. Currently it happens at least once per month. This is torture. I'm getting ready to switch to a different cloud storage provider. 

Hey alex g.33, thanks for the nudge here and sorry to hear about this.

Do the steps that the OP provided above, help at all?

HannahI've tried OP's steps in the past and they did resolve the problem, but only temporarily, and the re-indexing takes a very long time so it's not something I want to be doing on a regular basis. Fortunately I can often resolve the problem by quitting the dropbox  app and restarting it. I now have to this pretty much daily or the dropbox sync speed will drop to 16 KB/s even though my internet service clocks 160 Mb/s. 

I don't understand why it's taking years for Dropbox to even acknowledge this issue let alone do anything to fix it. I've seen many people post about this issue but it always seems like dropbox staff are just hearing about it for the first time. I'm starting to think that Dropbox has a policy that prevents support staff from publicly acknowledging their software's bugs.
