Page speed question

Hello,

Firstly thanks for your work on the plugin ??
What I do not understand is that Pingdom does not give a better page load time when using your plugin and it shows the same amount of http requests (if plugin loaded or not).

On the other hand, GT Metrix show a reduction in http requests and a light increase in load speed when the plugin activated.

Do you know why Pingdom does not see a reduction in http requests when using your plugin?
