I found the PC to be, as a whole, slower than the Alpha, especcialy on FP intensive code, but also on completely int code like postgreSQL, the respose times where twice as fast on the alpha, (Same amount of RAM, same database, same load = nil, same query). If you have both, use them! Just waiting for a good deal on a DS20 Good luck Regards Roberto To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
