Joomla optimization and security Most SQL injections that are written to hack a Joomla! website, try to retrieve data from the jos_users table. This way, they can retrieve the username and password from the super administrator of the website. Changing the default prefix into something random, will prevent (most / all) SQL injections.

Joomla optimization and security We can set the database prefix when installing our Joomla! website. If we already installed Joomla! and want to change our prefix we can use global configuration settings in admin side

General Optimization Variable Operations Operating on an initialized variable is 376% faster than operating on an unitialized variable. Constants are 146% slower than variables Local variables are 9.9% faster than global variables Incrementing an object property (eg. $this->prop++) is 3 times slower than a local variable.

Variable Operations

Operating on an initialized variable is 376% faster than operating on an unitialized variable.

Constants are 146% slower than variables

Local variables are 9.9% faster than global variables

Incrementing an object property (eg. $this->prop++) is 3 times slower than a local variable.

General Optimization Variable Operations str_replace is faster than preg_replace, but strtr is faster than str_replace by a factor of 4 Incrementing an undefined local variable is 9-10 times slower than a pre-initialized one. String Functions 'String' is 0.26% faster than "String“ strcasecmp() is 45% faster than preg_match() strcasecmp() is 13% faster than strnatcasecmp()
