How can I test the upload speed of Amazon S3 Transfer Acceleration for a specific file size?

Last updated: 2021-10-11

I want to use S3 Transfer Acceleration to improve the file upload speed to my Amazon Simple Storage Service (Amazon S3) bucket. I also want to compare the speeds between uploading directly to the S3 bucket and using S3 Transfer Acceleration. How can I do that?


To compare the general upload speed across Amazon S3 Regions, you can use the Amazon S3 Transfer Acceleration Speed Comparison tool. To test the upload speed of a specific file size, use the from the Amazon Web Services - Labs GitHub website.

Before you run, the following requirements must be met:

1.    Review your AWS Identity and Access Management (IAM) user credentials to be sure that you have the permissions to enable Transfer Acceleration. You need the s3:PutAccelerateConfiguration permission to enable or disable Transfer Acceleration. Additionally, you need the s3:GetAccelerateConfiguration permission to view whether a bucket has Transfer Acceleration enabled. For more information, see Requirements for using Amazon S3 Transfer Acceleration.

2.    Enable Transfer Acceleration on your S3 bucket.

3.    Install and configure the AWS Command Line Interface (AWS CLI) on your machine.

Note: If you receive errors when running AWS CLI commands, make sure that you’re using the most recent AWS CLI version.
