Thanks to your tool, I’ve managed to bring load times below 1 second on our site. Granted this test was done using FIOS connection but our site is quite image heavy and serves a number of CSS and JS scripts (~1MB of data on average). It was hovering at around 4 seconds before. Took awhile to pull this off but worth it imo
Techniques I found that brought the most noticeable benefits were minifying JS and CSS, as well as merging small images into a CSS sprite. Minifying the actual HTML content and removing line breaks also seemed to speed up render times a bit.
