Optimization Tips
Use includes() or preload() to load associated records - Eliminate N+1 queries and reduce database load
Use includes() to eager load associations - Eliminate N+1 queries and reduce database load
Use joins() when you only need to filter, not access associated data - Eliminate N+1 queries and reduce database load
Use preload() when you don't need to query on associations - Eliminate N+1 queries and reduce database load
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.
