Re: Improving performance by timing each rule?

[Matt Jonkman <jonkman () bleedingthreats net>]

Yes, chapter 7 rules!  :)

6 is good, but it's no 7...

Seriously, I agree with you OlRoy. That book came out better than any
I'd ever read before, and I'm not just saying that because I wrote a
chapter. The other contributors to it (including Joel) put some
incredible info in there. Much easier to use and apply I think.

Glad you're enjoying it.
