Out of interest I tried the first test here add ack into the mix we
I've grown to like as a developer as it uses some nice sensible
defaults for every day use avoiding svn etc.

Its a pure perl app so wasn't expecting it to be particularly quick
in the single file case, its much quicker in the multi file case, but it
seems to do quite well.

./grep-time-trial.sh
GNU grep 2.5.4
Elapsed time: 2 seconds

GNU grep 2.5.1-FreeBSD (base on 8.1-RELEASE)
Elapsed time: 2 seconds

BSD grep ( from ports 2.5.1 )
Elapsed time: 48 seconds

ack 1.92 ( perl 5.8.9 )
Elapsed time: 4 seconds

    Regards
    Steve
