How to Speed Up CodeIgniter App?

We can improve Codeigniter application speed with simple tactics. I will show very simple steps, which will improve your CI app speed.

Enable Gzip Compression

Go to application/config/config.php, Then Enable Gzip compression by setting compress_output value to TRUE in ci config array.

 $config['compress_output'] = TRUE;

Enable full page Cache

We can Enable full page Cache to entire Controller by calling $this->output->cache(30); in the controller constructor, or we enable it in function level by calling with in the method.

Full page Cache system create a Cached version of the HTML page in cache folder,

Cache folder should be writable by the web server

$this->output->cache(30); 
// Will expire in 30 minutes

Enable HTML output Compress

we gonna use CodeIgniter Hooks to minify HTML output, go to application/hooks/ create a file called compress.php, copy past the below code.

function compress()
{
 $CI =& get_instance();
 $buffer = $CI->output->get_output();
 
 $search = array(
    '/>[^S ]+/s', 
    '/[^S ]+',
     '<',
     '\1',
  "//<![CDATA[n".'1'."n//]]>"
  );
 $buffer = preg_replace($search, $replace, $buffer);
 $CI->output->set_output($buffer);
 $CI->output->_display();
}

till now we have created a hook function, now we have to declare it hooks config go to application/config/hook.php

$hook['display_override'][] = array(
	'class' => '',
	'function' => 'compress',
	'filename' => 'compress.php',
	'filepath' => 'hooks'
	);

The final step is going to application/config/config.php file, in the config array, enable hooks.
