I am having trouble optimizing performance on a woocommerce wordpress site. I have installed and ran Smush Pro. That part seems mostly successful but I think there are still some images that need work. My bigger issue is that I'm not seeing much of a result from Hummingbird. I have the page caching going but I'm struggling with the css and js assets. Can you assist in getting this right. The site referenced is a clone of our main site and I can allow remote access if needed.
