All Droplet’s are connected to a 1Gbps port, though it’s not a dedicated port as would be the case on a dedicated server where you’re on your own :-).
Speed Tests for Data Centers
Of course, the above are more so local tests (with a few smaller single file tests).
To test the connection from the outside within the Droplet, you’d probably want to test pulling down a file to the Droplet.
When pulling down the test 100 MB file on a fresh 64GB Droplet, it pulled down too quick to really do an accurate measure. It ran 107 MB/s, so the download took less than a second.
Pulling down a random 1 GB file from various locations resulted in the same overall average speed of 105-107 MB/s – so between 9.5 and 9.9s.
The 64GB Droplet comes with 9TB of bandwidth. From my own experience, speeds are pretty consistent in and outbound
That said, depending on what the Droplet is being used for, a number of factors can affect speeds accordingly. Higher levels of traffic to the server could impact speeds as it would on any server and network connection, depending on what visitors are doing.
Is there any specific use case you have in mind?
