I'm looking for good solution for joomla speed-up. I'm using currently JOT Cache and JCH Optimize. Both free. I like that you integrate all functions. What I miss is SPRITE loading of images offered by JCH PRO.
WHat is the demo site where I can see your optimized page vs same but not optimized? Your google chrome plugin shows only your logo (also on your demo sites).
Do you also offer help with setting? How are the images optimized? Is it WebP or something else?
