The performance increase depends on if the application(s) that you use are multi-threaded capable and if they are CPU intensive enough to matter. Having a second processor is nice to off-load some processing cycles to the other processor, leaving more cycles available on the primary processor for more important tasks (like RC5 :) In most cases, having a second processor in a web server is wasteful, but if you also run back-end applications (like database, web applications, etc.) it might help. // Linh Pham // http://closedsrc.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
