Original: The Midnight Call That Exposed a Silent Killer in a Laravel Store

Short summary

A Laravel store's products page became unusable with 5-minute load times instead of the normal 2 seconds, due to an N+1 query problem where the ORM was firing 1,500+ individual database queries per load. The inefficiency went unnoticed as the catalog grew from 40 to 500+ products, until one night it caused a complete outage. The fix: eager load relationships with Eloquent's `with()` method instead of lazy loading them in loops—a common trap that catches even experienced developers.

  • N+1 query problem caused products page to fire 1,500+ database queries per load instead of batched queries
  • Hidden inefficiency accumulated as catalog grew from 40 to 500+ products, turning a mildly slow page into complete outage
  • Fix requires eager loading relationships instead of lazy loading in loops—a pattern applicable beyond Laravel
