How to Speed Up CodeIgniter App?

You can use some step for sppdup codeigniter application.

Enable Gzip Compression

Enable full page Cache

Enable HTML output Compress

leverage browser caching

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.

File name : index.php

function compress()
{
$CI =& get_instance();
$buffer = $CI->output->get_output();
$search = array(
'/>[^S ]+/s',
'/[^S ]+</s',
'/(s)+/s', // shorten multiple whitespace sequences
'#(?://)?<![CDATA[(.*?)(?://)?]]>#s' //leave CDATA alone
);
$replace = array(
'>',
'<',
'\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 go to application/config/config.php file, in the config array , enable hooks.
