Hi @dtaht we did look into SQM recently while troubleshooting a bufferbloat issue on LTE but haven’t done any comprehensive throughput benchmarks.
Is there a benchmark using flent or iperf you can recommend?
Ideally with multiple flows, unfortunately the softirq system on Linux does cause performance issues for ‘single-thread’ situations.(See Vyos Build - My Repo - #5 by mcbridematt for an example)
