Our server is: 2cpu ( 8 core ). Ram 24GB. I used SSD .
I have about 400 site. In full admin, when I begin click to edit any site, I used Top command on centos to monitor, I saw mysql service used CPU very height ( about 150% ). After it loaded to edit site, CPU go to normal. And, when save any site, CPU go to about 150%.
If I used any user with some site ( max is 5 site ). It load faster.
