You could ask the maintainer of Chromium (chromium@FreeBSD.org) if this is = a known issue.

You can also look at this:

Onderwerp: Why do speedtest websites show much lower downl= oad speed in the Chromium browser?

When I run https://fiber.google.com/speedtest/ or https://www.speedtest.net/ in Firefox = - they show ~400Mbps download speed, and ~25Mbps upload speed.

Same websites, when run in Chromium, show ~50Mbps download speed, and ~25Mb= ps upload speed.


Something appears to be wrong with Chromium that it doesn't show the real s= peed.

Anybody has an idea what might be wrong?


Sorry for this being potentially off-topic here. I couldn't think of any ot= her forum where to ask this.


Thanks,

Yuri
