Awesome! Great changes so far…
The graphic optimization will definitely improve your load time. Depending on the amount of graphical objects, it can improve by a ton.
I have a website which I took from about 70 second load time to under 1 second off of graphic optimization. (Of course, all graphics were not optimized initially which made the load time looooooonnnnnnggg). I had about 20 graphic objects at the time as I remember.
