Depending on the services that you are running on your server, you mayneed to overcome different bottlenecks. For example, mail server deals with a largenumber of open files as well as a high I/O rate. Busy web servers are very networkintensive and tweaking network parameters will greatly enhance performance on aweb server.The freeBSD-performance mailing list (located at http://lists.freebsd.org/mailman/listinfo/freebsd-performance) is a good place to discuss performanceissues and the different methods to improve your system's performance.[ 99 ]
