Improving the performance of your CodeIgniter application is essential for providing a seamless user experience. Here’s a guide to help you optimize your CodeIgniter project.

✅ Step 1: Enable Caching

Use CodeIgniter's built-in caching system to store frequently accessed data.

$this->output->cache(10); // Cache for 10 minutes

✅ Step 2: Optimize Database Queries

• Use indexing for frequently queried columns.

• Avoid SELECT *; instead, specify only the needed columns.

• Use query builder for complex queries.

$this->db->select('name, email');
$this->db->from('users');
$query = $this->db->get();

✅ Step 3: Minify CSS and JavaScript

Compress and minify your CSS and JavaScript files to reduce loading time.

✅ Step 4: Use Autoload Wisely

Avoid loading unnecessary libraries, helpers, or models.

$autoload['libraries'] = array('database', 'session');

✅ Step 5: Optimize Routes

Define specific routes and avoid wildcard routing.

$route['product/(:num)'] = 'product/view/$1';

✅ Step 6: Use Content Delivery Network (CDN)

Load static resources like images and scripts from a CDN to reduce server load.

Conclusion

By implementing these strategies, you can significantly improve the speed and performance of your CodeIgniter application, enhancing the user experience and SEO rankings.
