Could you please provide evidence of your assertion (or, at the very least, a link)? As I said before, I don't doubt that there's overhead in running an SMP FreeBSD system, but I strongly believe that this overhead is overcome by the advantages of running such a set-up on a multi-processor machine. That having been said, if you have evidence to the contrary I imagine there'd be many that would like to hear about it. > Easy enough to avoid. > > Are you people stupid or delusional? Careful, mate. I tend to believe that it's wise, at least from a PR point of view, to assume you're in the wrong until proven otherwise. If you can prove otherwise, please do so. In the mean time, I suggest you adopt a more friendly tone: The people on this list are here to help you, but asserting that they're either stupid or delusional ain't gonna get you any help in a hurry. > DT -- Nick Withers email: nick@nickwithers.com Web: http://www.nickwithers.com Mobile: +61 414 397 446
