I’m @herberticus, lead developer of #LibreQoS. I joined not long after Robert Chacón and @mtaht got the ball rolling, added #IPv6 support, and created most of the #Rust parts, C parts, etc.. cc @rms @BrucePerens_K6BP

For a long time, #LibreQoS has only gathered traffic data at “enqueue” time - when packets enter #Linux TC.

This has led to LibreQoS’s monitoring occasionally looking inaccurate - and fails to highlight just how tight the #sch_CAKE / #FQ_CoDel + HTB (#HierarchicalTokenBucket) traffic shaping really is. A recent update changed this.

Read about it in the newest devblog post from @herberticus

In 2025, we launched the original #LibreQoS #Bufferbloat #Speedtest to give users and #ISPs a clearer way to measure #latency under load, not just raw #bandwidth.

Now, we are releasing Bufferbloat Test v2.0: https://libreqos.io/2026/03/23/libreqos-bufferbloat-test-v2/

We are dedicating this release to @mtaht

Thanks for posting this, @jzb et al at #LWN:

"This release includes many capabilities that reflect ideas and direction long championed by our late colleague, @mtaht.

They also announced the release of the #LibreQoS #Bufferbloat #Speedtest v2, also dedicated to #DaveTäht. It runs in a user's browser to look at "#latency under load, #jitter, loss & what those things mean for the kinds of traffic people actually care about: #browsing, #streaming, video calls, audio calls, backups, and #gaming".

The @mtaht Memorial Testbed of Coast-to-Coast-to-Coast Low-Earth-Orbit Satellite Networks (CCCLEO) was just shared on #Starlink
