I have a Magento CE 18.104.22.168 which is used to run a website containing 130,000 sku's . Our issue is the website seems to load slow. We have it hosted on an Amazon AWS cloud with plenty of RAM and processor speed. Yet still it is slow. We also setup Redis to cache the database in hopes it would speed up the site. However it still seems to load category pages slow.
We are wondering if anyone else has fasted this and what solutions they tried?
