Professional Profiling Without the Bloat

atec Profiler is exactly what I was looking for — a lightweight, focused plugin that gives me deep insight into how long each plugin and the active theme takes to execute.

It works by injecting two micro-profiler scripts into the mu-plugins folder, so it captures performance as early as possible, which is critical for accurate measurements. You can see total plugin load time, theme time, and even page processing time — all without adding overhead.

If you’re trying to troubleshoot bottlenecks or understand what’s slowing down your site, this plugin belongs in your toolkit.

Highly recommended.
