it won't index.php causing problem directly, that's file links together.

the chances have installed plugin using lot of resources display heavy usage on index.php because that's people access when using site.

the best way ask ssh usage, can @ whats going in..

joomla doesn't use lot of system resources out of box, bad plugins do.
