Hey John,
One more follow up and then it's bedtime for me. I wanted to further this
discussion just a little bit more by implementing the mmap solution that I
applied to perl to ruby instead. Now all of a sudden, ruby is much much
faster. My ruby source code follows:
Goodnight!
# ruby -W0
last;
}
$i ++;
}

In most cases the short answer is yes.
I have problems with your wording however given the 'geek' that I am. 'At
one time'
Sorry, it's 5:00am here and needless to say it's wy past my bedtime and
I'm making mistakes.
The comparison should have been between both ruby versions ugh.
I'll let you play though. Have a great night.

It's not always beneficial. There are cases

Thanks.
The data is way to small tbh
Thanks for the geeks on the lists who pointed out a lot of problems to
me.
I want to add the description why I want to make this benchmark. And I
tried to use mmap() for reading file but I have got no benefits from it.

Hello Paul
Do you mean by undef $/ and with <$fh> we can read the file into memory
at one time?
$/ is the input record separator, newline by default.
If undefined that means that the whole file is treated as one single record.
Yes that would be faster
Thanks Paul. I am surprised that mmap has that huge IO advantages
comparing to the classic way. So ruby take more benefit from this mmap
calling. Just get learned from your case.
