This goes without saying. It's the difference between programmers and software engineers. Nevertheless, there will continue to be a performance differential between FreeBSD and Linux. I personally don't think it's a problem; optimizing that area is optimizing noise. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
