Subject: tickless and HZ=1000 throughput advantage?
Date: Sat, 19 Sep 2009 15:47:24 +0100 [thread overview]
Message-ID: <6278d2220909190747n62f7036dj2e5231fcdc4730fb@mail.gmail.com> (raw)
On tickless kernels, is the general consensus that for non-embedded
systems, selecting HZ=1000 gives slightly more throughput in
particular situations than HZ=100 or 250, due to finer timer
intervals/granularity?
(low HZ used to cause problems with low-rate QoS packet queues when
timer scheduling was selected)
Thanks,
Daniel
