[Theme: Eudora] Page speed problems

Hello,

I bought Eudora theme few months ago. Globally, I am statisfied except this page load time problem. However, my grades on GTMetrix (https://gtmetrix.com/reports/www.rototec.com/S6bOhsI2) aren’t so bad, my pages are terrificly slow to load.

Someone can help to resolve this problem and allow me to optimize it ?
