MUST HAVE Plugin

My shop had become so slow it was not just painful, it wasn’t working properly. Anything that pulled info from the database was a crawl, or worse would fail. Product edits would either take a minute to save or would return Page Not Found. After much searching and reading for others having these issues I found mention of this plugin. Decided to give it a try, what was the worst could happen? Glad I did. The difference was immense. Pages in the back office load near instant. Products and orders load near instant. Everything on the backend is faster. Which no doubt means the front end speed has increased as well.
