Blackhat Why is my Blocking time so high

[KingOfDCP]

Hello,

I made many test via gtmetrix and noticed that my blocking time is so high. You could see in this picture

How can I solve that problem? I tried google something but no result. Could any one explain it for me and guide me how to fix it?
