Ehm, yeh... I'm testing this on an online yet practically secret website, so there's little to no traffic metrics to give me any sort of indicator on whether or not the plugin is actually working.
I've got a sub-domain successfully set up with an approved health check. Now how can I confirm whether my setup is working or not without using some sort of advanced speed measurement tool?
Perhaps you could recommend a free image-heavy theme that makes it easier to tell load times apart.
