Nice tool

I must say this plugin does what it’s supposed to. After multiple passes you do get different results but it is a great to to get an approximate load time of plugins.
It’s a great way to see what plugin may cause slowdowns also its a very good diagnostic tool to tell if a plugin is good or not.

Just keep in mind that the times are not 100% correct so the plugin should be used as a nice reference point for further site optimizations.
For example, it’s a great way to see how Jetpack is a huge resource hog etc.
