Spaces Max "bandwidth" throughput

Hello,

I recently did a large backup of some very large files (most between 2GiB and 5GiB) totaling around 2.4TiB to a Spaces bucket. The upload went smooth enough using s3cmd and completed overnight. When doing a test download (again using s3cmd) I am noticing that the transfers seem to cap out at around 250-300mbps. These are transfers across the Internet and not to any Droplet. I was wondering if there is any traffic shaping or other limitations to throughput from Spaces across the Internet?

Hi Jarland, I am currently connecting to the sfo2 datacenter from Sacramento (~100mi). Our connection is a symmetrical 1Gbps connection (via AT&T). For the purposes of this test these speeds are adequate but it just got me wondering. On our tests to Amazon S3 we saw slightly higher speeds (~350-400mbps). Again, not the end of the world, was just wondering.

Hey friend,

Thank you for bringing this question here. Though some rate limiting exists at very high request rates, there are no limitations to actual transfer speed on the Spaces product. I would expect the range you’re seeing to be fairly average. It’s not too terribly common that you can get 1Gbps on both end points and every network system between the two points, unless the two points are very near each other physically (and even then upstream paths are a factor).
