| <h2>PageSpeed Filter Examples</h2> |
| <p> |
| Here are some of the most useful PageSpeed filters. Each one has |
| a simple HTML example attached; click "before" to see the |
| original file, and "after" to see what PageSpeed produces |
| with that filter (and only that filter) enabled. The two |
| versions should look exactly the same, but the "after" one will |
| be (slightly) speedier. Use "view source" to see |
| the PageSpeed difference! |
