Do you mean an AMD K6-2 300, running with 100MHz bus (the usual configuration)? If so, I think you will find it much faster in general than a PPro 180. The area where the PPro will come closest is floating point; AMD's floating point before the K7 is very poor (though the 100MHz bus is a win for processing big arrays). Integer performance is likely to be at least 25% better on the AMD. And you can probably cheaply upgrade the AMD to a 400+Mhz version. > Does FreeBSD take advatage of the Pentium Pro's wider > bus? I didn't know it had one! The PPro's big advantage was the on-chip cache running at processor speed, but if processor speed is 180MHz that's not such a big deal now. -- Richard To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
