It is 25 times slower than GNU grep ;-((((((( $ time /usr/bin/grep foobar /var/tmp/mailbox >/dev/null 0.90 real 0.78 user 0.12 sys $ time /usr/local/bin/grep foobar /var/tmp/mailbox >/dev/null 24.31 real 22.36 user 1.69 sys (/var/tmp/mailbox is 81MB large). I often use grep for large data (in main memory). I don't care about the GNU license. I care about poor performance. -- Wolfram Schneider <wosch@freebsd.org> http://wolfram.schneider.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
