Howdy,
All versions that I've been using, are slow when I try to access the menu "administration", everything works fine and fast, except that menu.
I had a 3.4x version i think, and upgraded to 3.9.4 and the issue still remains.
I have no error in apache error log, no idea where to start.
I've saw some people on the web complaining about this aswell, but no solution that could make this work.
All tables are mysql, and innodb.
Thanks in advanced,
