User Case: Why Is My Dropbox Upload Speed So Slow


Hello guys, does anyone facing problem with slow uploading to Dropbox? I'm using 1Gbps connection uploading speed max around 3Mb/s, compared with Google Drive with my connection up to 80Mb/s. Already tried upload via Dropbox web, Dropbox Apps, Cyberduck, Zoom Uploader and all speed still same. Transferring 16TB data from Google Drive using Multcloud also average speed around 3Mb/s. Dropbox really capped limit or what? Seriously in 2018 with that speed?

- Question from Dropbox Community

What is Dropbox?


Produced by Dropbox Co., Ltd, Dropbox is a web-based file sync service that allows users to store and share files and folders.

As one of the most popular cloud drives in the market, Dropbox has gained a large user base around the world. The reason why Dropbox is so popular is that Dropbox has an absolute advantage in storing a large number of files. Meanwhile, you can share and sync files easily even if you are a free user.

Nevertheless, there are two sides to everything: the pros and the cons. Although Dropbox provides convenience, it makes users frustrated, especially when the Dropbox slow upload issue happens. If it is a small file, uploading it on Dropbox will just take several seconds; however, when it comes to large files, it will take 10 to 20 minutes to upload on Dropbox. So, what causes the problem of slow upload speed on Dropbox?
