Hi Chris,

the Blocking time is "the delay between when the browser realizes it needs to download a resource to the time that it actually starts downloading the resource".

You'll find helpful information here:

Hope this helps.

Hi Raff,

thank you for these elements.

Do you know some other reasons of blocking time, apart the one described in the link above (number of TCP connections in the browser) ?
