Plug in Speed ‑ Maximize Speed

I'm going to give this app a 5-star even though I removed it.
The reason I removed it is my theme was already well optimized. The developer spent considerable time analyzing why the app didn't do much of anything for my store... and it was because I already have strategically optimized code.

NOT THAT my store is perfect... it's just the way this app does things was not going to help my site.

I think the concept of how the dev is approaching this is smart. And for some themes, it will help.
I gave the 5-star because the developer is a pro and that says a lot to me.
