Reducing Laravel Permission Queries Using Redis (Benchmark Results)

Laravel permissions work great… until your application starts to scale. If you're using role/permission checks heavily, you might be hitting your database more often than you think. In this article, I’ll show you a simple benchmark comparing the default behavior vs a Redis-based approach.
