Trouble is, your report has no specifics as to what is faster or better, and even you don't recall where it's from, so it's of nearly no more use than rumors. I'm not trying to be offensive, but (unless you have some reason to assign more importance to your statement, that you haven't passed on to us), this kind of stuff is misleading to folks. Those "test reports" could very easily have come from biased benchmarking, something we're all familiar with. The fact that NCR chips show up in many interfaces, well, they ARE cheaper, aren't they? You have to have at least some kind of detail in reports such as yours, to make the data believeable. ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@picnic.mat.net | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run picnic (FreeBSD-current) (301) 220-2114 | and jaunt (Solaris7). ----------------------------+----------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
