Joomla is a wonderful Content Management System (CMS), but
sometimes websites created in Joomla can be slow. At times the graphics
won't even render.
Computers have always had a trade-off between
cost, speed, and space. If you have enough money, you can buy all the
speed and storage you need, but generally, people and business must
perform a three-way balancing act between cost, speed, and space. The
trick to speeding up your site is to figure out where the problem is in
the balancing act and fix it.
