Hello,

Thank you for your patience.
Would you please be able to post the logs gathered when you do a speed test? The last link of my forum signature explains how to use our tools to generate the ZIP to post here.

Also what is the computer doing when the test is performed?
Are you playing a video, is content on your monitors static...? I would need details to understand the setup.

Network speed is part of the suite of tests we run before making a release. We use a tool with machine-to-machine stress test to rule out Internet, ISP or other third party bottlenecks.

Kind regards,
Alban
