amazon-s3 - 从 Amazon S3 下载 Assets 的速度取决于哪些因素？

Question

我们可以从 Amazon S3 下载文件的速度有多快，是否有上限(他们会在同一用户的所有请求之间分配上限)，还是仅取决于我的互联网连接下载速度？我在他们的 SLA 中找不到它。

它还取决于哪些其他因素？他们是否在某种程度上限制了数据传输速率以防止滥用？

这已在最近的 Amazon S3 中得到解决团队帖子Amazon S3 Performance Tips & Tricks :

First: for smaller workloads (<50 total requests per second), none of the below applies, no matter how many total objects one has! S3 has a bunch of automated agents that work behind the scenes, smoothing out load all over the system, to ensure the myriad diverse workloads all share the resources of S3 fairly and snappily. Even workloads that burst occasionally up over 100 requests per second really don't need to give us any hints about what's coming...we are designed to just grow and support these workloads forever. S3 is a true scale-out design in action.

S3 scales to both short-term and long-term workloads far, far greater than this. We have customers continuously performing thousands of requests per second against S3, all day every day. [...] We worked with other customers through our Premium Developer Support offerings to help them design a system that would scale basically indefinitely on S3. Today we’re going to publish that guidance for everyone’s benefit.
