Hardcode to make WordPress faster
Hardcoding is generally not a good practice, however in the case of an established website, hardcoding your blog url, site url, template path and stylesheet path will make your blog run faster.
When a function such as bloginfo('url') is called, WordPress executes a query to your database to get the value, excepted if the value can be found on your wp-config.php file.
To hardcode those constants, edit wp-config.php and paste the following (Don’t forget to change the values!):
define('WP_HOME', 'http://www.catswhocode.com'); // blog url
define('WP_SITEURL', 'http://www.catswhocode.com'); // site url
define('TEMPLATEPATH', '/absolute/path/to/wp-content/themes/cwc5');
define('STYLESHEETPATH', '/absolute/path/to/wp-content/themes/cwc5');
