TTFB very Slow - Help Please

Hello guys,
I need your help, I’m at a time looking for that error that’s going on all my sites I’m using easyengine and I am not found, I am very sad on to it! Already I sought almost all tuotoriais Easy Engine and unsuccessful. The site is they are with a server response delay in 2s, the more often, in addition to having a time of waiting in all elements. What can it be?

We’re having the same issue with our sites. It seems to be a problem with the 301 redirect - and seems to happen particularly for www based domains.
