Subject: latency limiting to 4ms?
Date: Mon, 28 Feb 2011 06:19:50 -0700 [thread overview]
Message-ID: <87wrkkpa89.fsf@cruithne.co.teklibre.org> (raw)
I'm about to get on a plane but I saw this thread on lkml go by:
http://groups.google.com/group/linux.kernel/browse_thread/thread/b0add1502aafa46f/28dd3798b3d5e4f9?lnk=raot
Where the proposed sched_fifo_ewma.c code in that thread:
"Well, with 10ms buffer timeout latency goes to 10-20ms on 54Mbit wifi
link (zd1211rw driver) from >500ms (ping rtt when iperf running same
time). So for that it's good enough. "
And, well, I'd like to go for 4ms across the entire transmit
range. 10-20ms is *just barely* on the wrong side for voip and audio
applications, and the above stat is being measured at 54Mbit.
Someone care to leap in over there?
