Re: Slow upload speeds on Windows 7

The reason could be many things. Let's start with the question, was the Ookla speed test server at the same distance as Dropbox's server? The answer to that would be maximum time no as speed test servers are hosted very near to customers in ISP network. They do not give real information like say you have 10Mbps connection, but will you really get 10Mbps once you cross your ISP's network? The answer is NO. No ISP will guarantee that once traffic leaves their network. So thats the connectivity part.

Secondly, it is latency that would be very harsh on data transfer speed. Even if you have 10Gbps connection, you can transfer at very low speeds because of how TCP works (a widely protocol used to transfer data). You can search these terms if you want to understand them in deep: "calculate tcp throughput with latency" or "tcp speed calculator according to delay".

Third, different speeds for different paths. I have seen this in the past many times. In your question, you have not mentioned your actual/bought/committed internet speed. I have seen ISPs who would grant you different speeds based on different destinations. Like, for Google/Youtube, they might have a dedicated connection with them and since they pay for that connection at a almost fixed rate every month, they want to utilise that connection as much as possible. So they provide uncapped/more speeds as compared to the committed speeds. I have seen connections with 10Mbps committed speeds getting 100Mbps on youtube to se videos and on microsoft to download windows/office updates.

So these were some of the reasons you can get different speedtest results. You cannot do apple to apple comparison between different destinations.

If you want to dig deeper into this, we can do that but before that, I would need few more information like whats your committed/bought internet speed, who is your ISP (My experience in networking domain helps me in knowing ISPs behaviour and how their service would be), etc.

Hi team,

I am having issue with uploading files to drobox and  when i check speed test that are within specification 

My Isp is not able to address the issue as we have tried uploading via browser and desktop app as well on computer but the uploading speed is typically slow 

I have confirmed all the settings are intact in my drobox as the bandwidth is not limited and all other settings are intact

Now what troubleshooting my isp should do to address the issue as the speed test and tracert everything is within specification and can not see any packet loss as well

Thanks in advance 

I have a Gigbit connection connection at work, and my PC is is very fast, yet Dropbox is very slow to sync, and my 3TB business account will take a week to sync! I have not limited speeds in the Dropbox app.

See attached screenshot.
