This book is terrific! We were having problems with mod_perl memory usage and performance with our new website. This book gave us great ideas on how to implement startup.pl scripts, Apache::DBI, and many other Apache parameters. But the biggest payback was in the profiling of our code. The book suggested problem areas (such as slurping files), and provided reference to Apache::DProf which is a beautiful tool for profiling. The end result has been tremendous performance increase. Well worth the price (and even the quick shipping charges), this book is very timely! Kudos to Geoff, Paul and Randy on a robust, selfless and important effort!
