Finally fixed: "the random waves of suck" bug that's plagued @LibreQoS for 3 years.
I wrote up the journey - paying tribute to Dave, who battled this with me from
the start.

No more lock storms!

Fixing the Reload Penalty in LibreQoS

LibreQoS provides quality-of-experience (QoE) shaping and analysis for users, but it has had a major pain point for a long time. Since LibreQoS version 1.4 (released in November 2023), reloading users and the shaping tree could stall the processing pipeline, leading to bursts of packet loss. One of my colleagues even called it “random waves of suck” - a sudden burst of trouble across the network.

#LibreQoS Executive Dashboard:

We decided to display the global network-wide statistics as a simple heatmap.

Utilization, #QoO - Quality of Outcome, round-trip time, and retransmits follow a similar pattern.

A huge thank you to @nlnetfdn @nlnet for sponsoring this development.

LibreQoS Executive Dashboard

We’ve been working on something special for LibreQoS. The Insight heatmaps are popular - but feedback has indicated that sometimes they aren’t very clear - and it still requires a fair amount of effort to pinpoint problems.

Pion SCTP with RACK is 70% faster with 30% less latency

https://pion.ly/blog/sctp-and-rack/

#HackerNews #Pion #SCTP #RACK #speed #latency #technology

RACK makes Pion SCTP 71% faster with 27% less latency | Pion

In the RACK profile, SCP sustained 316 Mbps using ~0.044 CPU seconds, compared to 234 Mbps at ~0.056 CPU seconds before RACK. When normalized for CPU usage, this corresponds to a ~71% improvement in throughput per CPU, while max-burst CPU profiles remain comparable.
