Power impact of debufferbloatingPower impact of debufferbloatingPosted Sep 15, 2011 21:53 UTC (Thu) by BenHutchings (subscriber, #37955)In reply to: Power impact of debufferbloating by butlerm Parent article: LPC: An update on bufferbloat
Solarflare Ethernet controllers support per-queue TX pacing. This was meant primarily as a means to throttle specific processes that are given their own queues, though so far I don't think we've made any use of it. You probably don't put 10G network controllers in a real low-power system though!
In the absence of pacing, it might be more useful to vary TX interrupt moderation (if there are separate interrupts for TX and RX).
