I would like to see how long plugins take to load, as well as other aspects of the page (loops and database requests).
My webpage can take ~2-3 seconds to return the initial request. It seems high and I'd like to figure out how I can optimize it.
Also, as I understand it, every plugin is loaded on each request (even if it's not loaded for that page). Is this true? And if so, why is this the desired behavior? If a plugin is performing poorly it can bring the entire website to a standstill (this just happened to me: Website taking 30+ seconds to load).
