This article provides instructions on how to measure data transfer speeds when working with Qlik Data Gateway - Direct Access.

The information in this article is provided as-is and will be used at your discretion. Depending on the tool(s) used, customization(s), and/or other factors, ongoing support on the solution below may not be provided by Qlik Support.

Instructions

Log in to the Data Gateway Server
Using the attached PowerShell file (Create-Dummy-Data-File.ps1), create a 1 GB large file using the following command:

.\Create-Dummy-Data-File -Size 1024

You can increase the file size to 2 GB by using 2048 instead.

The PowerShell script will create a QVD file for testing purposes. The file includes randomly generated data designed to avoid network compression. It is recommended to generate the file on the Gateway server itself and upload it from there.

The file does not include any usable or valid data and should be deleted after the test, both from the local storage and Qlik Cloud.
With the file created, log in to your Qlik Cloud. Do so from the Data Gateway - Direct Access gateway server you want to benchmark.
1. Open the Qlik Cloud hub and select Add Dataset or Create Data Set
2. A window will open, select Upload Datafile
3. Select the QVD that was just created, and indicate the Space to upload the file. Do not yet upload the file.
4. Open the browser developer tools.
5. With the developer tools open, select Upload to begin the upload process.
6. Wait until the file is uploaded, then collect the har file (read more here).
Repeat the above two to three times in a row replacing the data file during the upload and also repeat during different times a day (for example at 8:00,10:00,12:00,14:00 and 16:00 hours).
Once completed, open the collected har files and search for temp-contents. You can use the file requests to calculate your results.

In the below example, we would consider the last five requests:

6. Collect the har files and use the qcs-speed-test tool to calculate the upload for each of the tests done, you can also share this information with your internal network team for further discussion.
