Slow Uploads Speeds on 1GB Dedicated Leased Line

I am experiencing less than 10MB/s upload on a connection which I have 1GB dedicated.

I can confirm the upload speed of my connection to any other server or speedtest is 1GB when testing.

I have enabled No Limit in the Dropbox app.

Dropbox support claim they do not throttle the connection.

I have 27TB of data online with Dropbox currently - I have been carrying out some reorganisation of large amounts of files and data online recently - will this impact current speeds?

Thanks for posting here today, @syntrak!

Can you please clarify what’s the app version and current syncing status of your Dropbox app? Is it indexing/syncing/up to date?

Did you start noticing this issue only after moving around a large amount of data?

Let me know, and we’ll have a look.

The best speed I have seen is 100MB/s on my 1GB leased line - which is not really very good, considering I consistently get 900MB/s on any other site I upload to, hence the reason to invest in a dedicated leased line 🙂

Current status is syncing on CloudSync app and Up to Date on the native app, which has Selective Sync activated.

Versions:

Mac: 176.3.5042

Windows: 176.3.5402

CloudSync (Synology): 2.6.1-2286

The speed has decreased since moving data around, yes.

I am seeing the same issues whether I use Dropbox native app on PC or Mac, or CloudSync on my Synology NAS drive.

All in all its extremely disappointing.

Please help! Thanks!

While most ISPs and speed test sites display their results in bits (kilo or mega), the speeds reported by Dropbox are in Bytes. Be sure to do the conversion before comparing. Your 100MB/s transfer speed as reported by Dropbox would be equivalent 800Mb/s.

Also, each file that you upload is hashed, compressed, then transferred, encrypted, and stored on the Dropbox servers. That entire process is included in the aggregate MB/s speed that's displayed in the Dropbox sync status. In other words, the speed reported by Dropbox is not just a transfer speed, but the speed at which the entire process is being completed.

If thats the case as you say, then why on the weekend I saw 102 MB/s and now its currently uploading at 1.8MB/s ?

If I am uploading 90GB of data to another internet based server (not Dropbox), it will take me 12 minutes on my 1GB leased line.

Definitely something strange going on server side with Dropbox. Who in Drobox would be able to examine the connectivity server side and analyse the exact issue?

Thanks!

Hi again, @syntrak!

What Rich mentioned above is correct.

Also, if you’re seeing 100 MB/s of speed one day and not the next, then this is most likely not an issue on Dropbox’s side.

However, if you want our support team to check this further, you can open a ticket with them via this page. If you do this, don’t forget to send us your ticket number here as well, so that we can leave an internal note to our team.

Thanks.

Hi there

Support ticket is: 22286168

Speedtest is showing 900 Mb/s and down. No issues on any server.

Dropbox has slowed down to a snails pace now, 3 Kb/s.....

Please see what you can do?

Thanks!

Im also noticing that large folders won't move to a new location within Dropbox, when using etc web browser.

Status says moving, but it doesn't complete. Folder contains 500-800GB of data.

Any ideas as to why this is?

Hi @syntrak, thanks for the ticket ID. I can see it's been forwarded to a specialist team, who will investigate this matter in more detail on their end.

I've added your comments onto the ticket so that they are aware you've been in contact on the Community.

I have heard nothing from anyone at Dropbox. The speeds are still rediculously slow.

Do I have to start searching for a viable alternative to Dropbox? I hope not!

Walter

Hey @syntrak, thanks for the nudge on this.

I just checked back on your ticket and I can see that the expert handling your request has responded.

I'd recommend getting back to them through email for further assistance, if needed.

syntrak

Yes an utterly useless reply as they have obviously not even checked their end. I have replied.

Just to prove that my speed is as I have described.

Dropbox still ultra slow on both native app and Synology Cloud Sync.

Jay

Thanks for the info. As you're still in contact with the specialist team, I'd recommend continuing with them as they have access to more account and device-specific information.
