Yes. /dev/random is now just an alias for /dev/urandom (or vice versa). You must have a fast machine to get 10MB/sec. I see the following speeds (using a better reading program than dd; dd gives up on EOF on the old /dev/random): old /dev/random on P5/133 5K/sec old /dev/urandom on P5/133 244K/sec old /dev/random on Celeron 366 overclocked to 5.5*95 25K/sec old /dev/urandom on Celeron 366 overclocked to 5.5*95 970K/sec new /dev/*random on Celeron 400 overclocked to 6.0*75 270K/sec Bruce To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
