Performance

Your Laravel app is probably slow because of database queries. Mine was too. Here's everything I learned fixing it.

Redis is more than a cache. Learn patterns that actually improve performance.

Stop making users wait. Push slow tasks to the background.

Fast JavaScript makes happy users. Here's what actually matters.

Stop serving desktop images to mobile phones. Save bandwidth and improve speed.

Slow queries kill apps. Learn to read EXPLAIN and fix the common problems.

Cache invalidation is hard. These patterns make it manageable.

When things break at 2 AM, you need a systematic approach.

Good logs help you debug. Bad logs just fill up disks.

Protect your API from abuse without blocking legitimate users.
