Trouble with Codeigniter 3 Performance

I hope you're all having a great day. I've been using Codeigniter 3 for my projects, but I've noticed that it's not performing as fast as I'd like it to. I'm curious if anyone else has encountered this issue.While I'm aware that Codeigniter is known for its speed, [font=Söhne, ui-sans-serif, system-ui, -apple-system, 'Segoe UI', Roboto, Ubuntu, Cantarell, 'Noto Sans', sans-serif, 'Helvetica Neue', Arial, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji'] License Number DMVNOW Portal [/font] my experience has been a bit different. Are there any common reasons why Codeigniter 3 might be running slow? Or perhaps some optimizations that I can apply to improve its performance?

I haven't noticed any issues with CodeIgniter itself. I'm currently working with 4.
You should look at the database. Over time more data is added and tables need to be optimized or indexes added. Also if the site is on a shared host or shared db server other sites will have an impact on performance. Although that's harder to prove without help from the host.

You may need to re-factor your code, run test to see where your bottle necks are ( F-12 key ).

Try to configure and setup OpCache in php.ini to speed it up.
