I have a remarkable experience in using Litespeed Cache for WordPress on Non-LiteSpeed servers.
I can visually observe a dramatic decrease in page load time. Along with it, a single provides all forms of functions like Lazy Loading, Minifying (w/o breaking the code), Render blocking resources and much more.
Those who really care about the site loading speed must try LiteSpeed for WordPress even if you don’t have a LiteSpeed server.
Note: I am sorry that I forgot to take screenshots before and after the plugin. But I am installing over all my new blogs. So, I will update in the future for sure.
