Boost Laravel Performance: My Query Runs 30s Faster! I replaced `whereNotIn()` with `leftJoin()` - and my query ran 30 seconds faster. The table I was searching for had 800k+ records. Here are 10 quick ways to optimize Laravel queries: - Use `leftJoin()` instead of `whereNotIn()` - Faster and more efficient. - Replace `whereIn()` with `whereExists()` - Saves memory. - Select only needed columns (`select()`) - Avoid `User::all()`. - Process large data in chunks (`chunk()`) - Don’t load everything at once. - Use `pluck()` instead of `get()` - Faster for a single column. - Check records with `exists()` instead of `count() > 0`. - Use `upsert()` instead of `updateOrInsert()` - Fewer queries. - Paginate results (`paginate()`) - Avoid fetching all data. - Cache frequent queries (`cache()`) - Reduce database load. - Avoid eager loading in loops (`load()`) - Load relationships efficiently. Every millisecond counts. Small changes = big performance gains. :)
