my Joomla site is too slow. It approximately uses 8 to 10 s to load main page. I am using xampp. template protostar. PC core i7. OS windows. JOOMLA 3.15. Is it normal ??
In addition to the above mentioned answer I uncommented the
bind-address="127.0.0.1"
setting in the MySQL configuration file (my.ini).
This brought an increase of execution speed to my local Joomla installation on Windows 8.1.
