Public S3 speed test

Test download throughput to ClearStreamer from the computer or server where you plan to use the service. Choose an available region below and download a test object using the supplied public demo credentials.

These endpoints use the real S3 CDN path. Results depend on your network, the route to the selected region, and other people testing at the same time.

Available regions and credentials

The keys below are public, shared, read-only demo credentials. They work only with the clearstreamer-speedtest bucket and require no IP whitelist. Use them for these tests, not as replacements for your own service credentials.

Your private service endpoint and credentials are in your welcome email; see Endpoint & credentials.

Use the current keys on this page

Demo credentials may be refreshed. If a previously working test returns an authentication error, reload this page and copy the current pair for your chosen region.

How to run and read the test

  1. Install AWS CLI v2 if needed. aws --version should report aws-cli/2.
  2. Start with the region nearest you. Copy its complete command block above.
  3. Wait for the command to finish. It downloads 1 GiB, discards the data, and prints elapsed time. It does not save a large file to your disk or change your saved AWS configuration. A quiet terminal during the download is normal.
  4. Read the real elapsed time, rather than CPU time (user or sys). For this 1 GiB file, average throughput in Mbit/s is 8589.93 divided by elapsed seconds. For example, 20 seconds is approximately 429 Mbit/s.
  5. Repeat two or three times, then compare another available region. Use each region's own key pair so its test traffic is counted correctly.

These are S3 downloads, so you do not need an AWS account. The us-east-1 option is the S3 signing region for both endpoints; choose the geographic region using the endpoint hostname. Other S3 clients can use the endpoint, bucket and keys in the tables with path-style addressing.

Test files

Every available endpoint serves the same immutable synthetic files. File names use MB/GB, while the actual sizes below are binary MiB/GiB.

Object Exact size Use
10MB.bin 10 MiB Quick connectivity check
100MB.bin 100 MiB Short download
1GB.bin 1 GiB Starting point for a speed test
10GB.bin 10 GiB Longer test for a fast connection
small/00000.bin through small/00999.bin 1,000 × 64 KiB Small-object testing
MANIFEST.json Manifest Object sizes and SHA-256 checksums
ATTRIBUTION.txt Attribution Dataset provenance

To change the transfer size, replace 1GB.bin in the command with another file from the table. A 10GB.bin test transfers 10 GiB; its average Mbit/s is 85899.35 divided by elapsed seconds. Use a larger file if the smaller one finishes too quickly to give a useful measurement.

What should I send to support?

Send the region, test file, elapsed time, your city/country and ISP, whether the test ran on your computer or a server, and the approximate test time with time zone. If the command failed, include its error message. Do not include your private ClearStreamer service credentials.

Why is my result slower than my plan's tier?

These public endpoints are shared and have no account bandwidth cap or reserved capacity. A result measures the path from your test machine at that moment; it does not guarantee the throughput of a paid plan. Try again and compare regions before drawing conclusions from one run.
