You cannot control external resources. Facebook and Google are always fast to load.

Ah, thank you.
Is GtMetrix the best way to know the performance of a website or do you have another website which can help me more ?
It points configuration issues just fine in easy to assess form. It is free compared to holding a machine across one ocean to meter user experience for one single site.
