Optimization Tips
Add single_column index: add_index :users, :id - Fast lookups for id = value queries
Specify only needed columns instead of SELECT * - Reduced memory usage and faster data transfer
Index Optimization - Review indexes on the 'users' table. Consider composite indexes for WHERE clauses.
