This machine will hopefully provide shell accounts, ftp access, web service, and possibly POP mail service for a large number of people (>500). 3) What utilities provide the best picture of system performance? I've used 'top' and I've run 'lmbench' and 'bonnie' before to beat on a system, but I was wondering what other people use to gauge system performance. Any advice from any other large FreeBSD sites is appreciated. Thanks, Craig
