I'm on a mission to boost the page loading and general performance of a WordPress site I recently took over management of. Currently hosted on AWS EC2 Linux instance with latest Apache, PHP, MySQL installed. Small ecommerce site, not huge traffic, but performance audits reveal some issues. Am experienced with WP but still developing with server admin. and performance optimizing. Researching online and have a "to do" list based on reports from Google Chrome Lighthouse, Pingdom, GTMetrix. But could use a little guidance on where the "low-hanging fruit" is so I can get this fixed ASAP. Any tips or insights appreciated. Thanks.
