Message-ID: <20071007090808.GB733@elte.hu> Date: Sun, 7 Oct 2007 11:08:08 +0200 From: Ingo Molnar <mingo@...e.hu> To: Jeff Garzik <jeff@...zik.org> Cc: netdev@...r.kernel.org, Ayaz Abdulla <aabdulla@...dia.com>, LKML <linux-kernel@...r.kernel.org>, Andrew Morton <akpm@...ux-foundation.org> Subject: Re: [PATCH 0/5] forcedeth: several proposed updates for testing * Jeff Garzik <jeff@...zik.org> wrote: > * I feel TX NAPI is a useful tool, because it provides an independent TX > process control point and system load feedback point. > Thus I felt this was slightly superior to tasklets. /me agrees violently btw., when i played with this tunable under -rt: enum { NV_OPTIMIZATION_MODE_THROUGHPUT, NV_OPTIMIZATION_MODE_CPU }; static int optimization_mode = NV_OPTIMIZATION_MODE_THROUGHPUT; the MODE_CPU one gave (much) _higher_ bandwidth. The queueing model in forcedeth seemed to be not that robust and i think a single queueing model should be adopted instead of this tunable. (which i think just hid some bug/dependency) But i never got to the bottom of it so it's just the impression i got.
