Don't scale Laravel Horizon blindly—tune it first

When Laravel queue systems slow down, the first instinct is often to add more workers. But according to a post on Freek.dev, the real problem usually lies in configuration clarity and a lack of measurement, not in scaling.

Stan Daniels shares a practical checklist for tuning Laravel Horizon that recommends a step-by-step approach. The list includes aligning timeout and retry_after values, verifying deploy hooks, and measuring real queue behavior. According to the article, adding workers before completing these basic checks may hide the problem rather than solve it.

The report says queue performance issues often come down to misconfigured values or missing instrumentation. A mismatch between timeout and retry_after can cause jobs to run unexpectedly again or get lost. Verifying deploy hooks, meanwhile, ensures that new releases restart queue processes correctly.

For teams running Laravel, the checklist serves as a concrete reminder: measure first, clarify the configuration, then scale. The article stresses that measuring actual queue behavior is more effective than blindly adding resources.
