[Smush Pro] How to see

Hello! I got Smush pro as a trial and it’s taking two day to bulk smush! Yes over 10000 photos. I need to delete some.

It says it 2 gb less now and it’s still counting, but I don’t see a difference in the size of all my photos which is at 4.2 MB. It was always at 4.2 even before I did the bulk smush. Will this app reduce the size of my Content size by content type: photo. The page size is super high and this is what I need to reduce as I keep hitting max CPU and physical memory usage all the time. see link below: https://tools.pingdom.com/#5ca03bfac0000000

Am I not setting the plug in properly or it won’t help with this at all?

Thanks so much!
