How can performance issues with ActiveRecord classes be addressed in PHP?

Performance issues with ActiveRecord classes in PHP can be addressed by optimizing database queries, reducing the number of queries executed, and caching query results where possible. Additionally, using indexes on frequently queried columns and avoiding unnecessary data retrieval can also improve performance. 

// Example of optimizing database queries by using indexes on frequently queried columns
// Assume we have a User ActiveRecord class with a 'username' column

// Before optimization
$users = User::where('username', 'john')->get();

// After optimization
// Add an index on the 'username' column in the database
// Then query using the indexed column
$users = User::where('username', 'john')->get();
