As the book front says, there are 14 Steps to Faster-Loading
Websites that are covered. It's very difficult to find any fluff at all.
The techniques are covered in priority order, those that produce the best
results first. Not all techniques will apply to all websites, but many
will. Also, many well known sites are compared for how well they
implement (or not) these techniques.

Each technique is backed by enough background to let you
understand why they work, and URLs are provided to allow you to experience
and test the concepts without having to do too much work.

I particularly enjoyed the author's note, on several occasions,
that a lot of things were either difficult or impossible with Internet
Explorer. Even though it remains the most popular browser, one has to ask
why? But I'll get off my soapbox.

I found this to be an excellent book. I'm able to apply what I've
learned to a variety of websites I have access to or tinker with, and I'm
not a webmaster.
