Codeigniter 3 is too slow

I have installed CodeIgniter 3,
My server configurations are,

• PHP 7.4
  
• Ubuntu 22
  
• Appache2
  

 The application is loading very slow. When i print something in the index.php its very fast not in the case of actual app.
It takes too long time to load the first file.
It happens for every click on the page. It takes 2-3 seconds from a click til page is loaded.
We have tried installing on another ubuntu server, but the issue remains.
Not sure how we can solve this.


Thanks for the help in advance.

Use your Web Broser's Developer Tools Network Tab to see whats slowing it down.

Turn on CodeIgniter's DebugBar it will also show you timings.

What did you Try? What did you Get? What did you Expect?

Hello,
Try to use memcached instead of redis
apt install memcached
apt install php7.0-memcached (change 7.0 with your php version)
then go to /application/config/config.php and chage this lines
$config['sess_driver'] = 'redis';
$config['sess_save_path'] = 'localhost';
with this
$config['sess_driver'] = 'memcached';
$config['sess_save_path'] = 'localhost:11211';

this config work with me
