Using the Amazon S3 Transfer Acceleration Speed Comparison tool

Focus mode
Using the Amazon S3 Transfer Acceleration Speed Comparison tool - Amazon Simple Storage Service

You can use the Amazon S3 Transfer Acceleration Speed Comparison tool to compare accelerated and non-accelerated upload speeds across Amazon S3 Regions. The Speed Comparison tool uses multipart uploads to transfer a file from your browser to various Amazon S3 Regions with and without using Transfer Acceleration.

You can access the Speed Comparison tool by using either of the following methods:

  • Copy the following URL into your browser window, replacing region with the AWS Region that you are using (for example, us-west-2) and amzn-s3-demo-bucket with the name of the bucket that you want to evaluate:

    https://s3-accelerate-speedtest.s3-accelerate.amazonaws.com/en/accelerate-speed-comparsion.html?region=region&origBucketName=amzn-s3-demo-bucket

    For a list of the Regions supported by Amazon S3, see Amazon S3 endpoints and quotas in the AWS General Reference.

  • Use the Amazon S3 console.
