McKenney" Subject: updated latency measurements Cc: linux-kernel@vger.kernel.org MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7BIT Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 856 Lines: 19 The latest version of my report which measures the latency of user-space processes running on Linux via a hardware device is available. This report measures the latency of the 2.6.14.2 kernel and compares it to a 2.6.14.2 kernel with Ingo's -rt12 patches. http://geek.vtnet.ca/embedded.html You'll probably just want to skip to the results of the high-load scenario here: http://geek.vtnet.ca/embedded/LatencyTests/html/results-ts3.html The graphs include: latency measurements, max latency, min latency, loadavg, and a measure of processor busyness. A separate histogram indicates measurement distribution. - 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/
