I’m working with a 20 year old blog that gets moderately heavy traffic, has an active comment section, and loads of old content that can’t be removed.
They’ve been principally opposed to any sort of significant monetization and have reached a point where shared hosting is hitting server limits. The site is powered by WordPress.
Any suggestions on optimizing the site for server performance are greatly appreciated. I’ve done the usual database optimizations, caching checks, and PHP memory increases. Anything else I should do?
