X-Sender: jono@stuart.microshaft.org To: freebsd-questions@freebsd.org Subject: FreeBSD benchmark question Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: X-Loop: FreeBSD.ORG Hi: We are testing a VALinux machine running Red Hat 6.2 against a FreeBSD machine running 4.3-RELEASE. The test consists of running a genetic search algorithm on both machines and using time to meaure the result. I have found the Linux box is much faster after running the search once and then firing it off again. So, the first run of the test the two machines are almost exactly as fast. But, the next time the linux box runs the test it is vastly faster than the FreeBSD box. I believe this has something to do with caching, but I don't know the specifics. Can this type of feature work on FreeBSD? I've enabled softupdates but that only helps a little. Also, the linux box seems to run the CPU up to 100% right off the bat when starting the test. This probably helps it complete the test quickly. However, the FreeBSD box runs the CPU up more slowly and never reaches even 75% usage. Is there a way to get the FreeBSD box to hog the processor right off the bat?
