From: Daniel J Blueman To: Linux Kernel Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 597 Lines: 17 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 -- Daniel J Blueman -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
