This is good information, but could you explain why you think that everyone should use caching? You don't mention testing in this article so is it safe to say that you don't? Do you have performance tests that show that the caching actualy matters for you application workload?

I do test for caching (though I must admit I write first, test later); I'll write that up in a later post. Similarly, I'll put up some comparisons to show the performance difference those changes have made :)

I think everyone should be caching as the speed of your page loads is fast becoming an even more important factor in people using/enjoying your site. Everyone (including myself) is getting more impatient in regards to page load speed, and every little helps. Also, you never know when you'll hit the frontpage on HN!
