Configuration to verify performance of S3 Transfer Acceleration

Here is an easy way to check the performance of S3 Transfer Acceleration.

S3 Transfer Acceleration is one of the options offered by S3, which allows users around the world to optimize the network performance when uploading and downloading data.

Amazon S3 Transfer Acceleration is a bucket-level feature that enables fast, easy, and secure transfers of files over long distances between your client and an S3 bucket. Transfer Acceleration takes advantage of the globally distributed edge locations in Amazon CloudFront. As the data arrives at an edge location, the data is routed to Amazon S3 over an optimized network path.

Configuring fast, secure file transfers using Amazon S3 Transfer Acceleration

In order to check the performance of S3 Transfer Acceleration, we will use the tool Amazon S3 Transfer Acceleration Speed Comparison for verification.


Diagram of verifying performatance of S3 Transfer Acceleration.

Create one S3 bucket.

Set S3 Transfer Acceleration to be enabled for this bucket.

CloudFormation template files

We will build the above configuration using CloudFormation.

Place the CloudFormation template at the following URL.

Template points

We will cover the key points of each template file to configure this environment.

Set Status of AccelerateConfiguration to Enabled

Define the resources around the S3 bucket in saa-02-002.yaml.

S3 Transfer Accelerationを有効化したバケットを作成します。

    Type: AWS::S3::Bucket
      BucketName: !Sub ${Prefix}-bucket
        AccelerationStatus: Enabled
      AccessControl: Private
Code language: YAML (yaml)

Configure the S3 Transfer Acceleration settings in the AccelerationConfiguration property. You can enable it by setting the AccelerationStatus property in the same property to “Enabled”. By default, this property is “Suspended”, which means it is disabled.


We will use CloudFormation to build this environment and check its actual behavior.

Create CloudFormation stack and check resources in stack

Create a CloudFormation stack.

For information on how to create stacks and check each stack, please refer to the following page

As a result of executing the above command, we have confirmed that the name of the S3 bucket created this time is “saa-02-002-bucket”.

Next, we will check the S3 Transfer Acceleration setting status of the bucket.

Enabling S3 Transfer Acceleration.

You can see that the Status value is “Enabled”, indicating that it is successfully enabled.

Evaluate performance of S3 Transfer Acceleration with tool

Now that the bucket is ready, we will use the speed comparison tool to check the performance of S3 Transfer Acceleration.

To use the tool, follow the steps described in the AWS official website.

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

Using the Amazon S3 Transfer Acceleration Speed Comparison tool

Create the URL according to the above. If we modify the “region” and “BucketName” to match our configuration, we will have the following URL.

After accessing the above page, the tool will start automatically.

Result of S3 Transfer Acceleration Speed Comparison.

As shown in the image, when the tool is run, it will start uploading data for testing from each region. The data upload is performed in such a way that the presence or absence of the S3 Transfer Acceleration setting can be compared.

From the results of the image, we can see that uploading from regions close to the Tokyo region (Tokyo and Seoul), where the S3 bucket is located, is less effective. Uploads from distant regions (Dublin and Frankfurt), on the other hand, are more effective, with up to a 2.5X improvement.


We have created an S3 bucket with S3 Transfer Acceleration enabled.

We also used an evaluation tool to verify the performance of S3 Transfer Acceleration in speeding up file transfers.

From the results of the verification, we confirmed that we can expect a speedup of about 2.5 times in regions far from the bucket.
