Memory bandwidth is much slower - hard to beleave.

I'm not shure what you expect, but we are talking about less than a millisecond. My AXPpci33 machine is not up so I can't compare. But my other machines (NetBSD/Solaris) are in a similar range. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
