What I Learned Debugging a Slow Site for a Client
One bloated plugin was responsible for 70% of the page load time. Here's how I found it and what you can do to avoid the same issue.
A client came to me complaining their site took 8 seconds to load. They had tried caching plugins, image optimization, even a new host. Nothing helped.
I ran a performance audit and immediately saw the culprit: a popular "all-in-one" plugin that packed 50 features into a single file. It was loading scripts on every page, even when none of its features were used.
I replaced it with three lightweight plugins, each doing one thing. Load time dropped to 1.5 seconds. The lesson: don't install Swiss Army knives. Use a dedicated plugin for each job, and always test with a performance tool before and after.
