Data-Heavy Laravel Applications

Making Laravel apps faster when the data gets big: queries, indexes, Eloquent, and aggregation.

  • MySQL
  • PostgreSQL
  • Eloquent
  • Performance

Problem

Apps got slower as datasets grew and queries got more complex.

Context

Laravel apps on MySQL and PostgreSQL with Eloquent, Query Builder, aggregations, and reporting-style workloads.

Challenge

The slowdown usually isn't one bug. It's the mix of app logic, schema, queries, indexes, and volume.

Approach

I profiled the slow paths, looked at query plans and indexes, cut unnecessary data loading, and reworked queries for large collections and aggregates.

Result

More practical performance on data-heavy Laravel workloads by treating the database as part of the architecture.

Lessons

A lot of 'Laravel is slow' tickets are really database tickets wearing application clothes.

Architecture

  • MySQL / PostgreSQL
  • Eloquent and Query Builder
  • Indexing strategies
  • Aggregation and reporting queries
