MIME-Version: 1.0 Message-Id: <1389671204703217@webmail34.yandex.ru> Date: Wed, 05 Mar 2008 10:46:57 +0300 X-Mailer: Yamail [ http://yandex.ru ] 5.0 Content-Transfer-Encoding: 7bit Content-Type: text/plain Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 723 Lines: 16 Hello all, everyone knows that there are three kinds of lies: lies, damned lies, and benchmarks. Despite of this obvious fact, recently I've tried to compare pipe performance on Linux and FreeBSD systems. Unfortunately, Linux results are poor - ~2x slower than FreeBSD. The detailed description of the test case, preparation, environment and results are located at http://213.148.29.37/PipeBench, and everyone are pleased to look at, reproduce, criticize, etc. Thanks, Dmitry -- 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/
