Apart from a faster blinking rate of the syscons cursor, I haven't seen much difference. This is my own personal workstation though, and it's almost never loaded too much :-/ - Giorgos On 2002-01-31 14:22, Storms of Perfection wrote: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
