This article is actually right that I downloaded the old version for Windows (would not happen on another OS, as there are maintained packages in most of the package managers).
But I just checked with the newer version and I didn't see a difference when testing with my 2.5GbE LAN (still 2.3Gbit UP and 1.9Gbit DOWN)
