# Relay Performance Best Practices

For when the data loads correctly but the app still feels slow

## What this does

The Relay code works, but the screen takes too long or redraws more than it should. This is the performance side: where queries go, how caching behaves, and how data is split up and filtered. Reach for it when you are tuning an app that is already correct.

### Top 3 things it does for you

- Work out where a query should live
- Cut down unnecessary re-renders
- Set up caching and fetch policies

## About Relay Performance Best Practices

Performance best practices for Relay applications, for optimizing data fetching, reducing re-renders, configuring caching, and improving time to first meaningful paint.

The ground covered is query placement, defer, pagination, fetch policies, garbage collection, fragment granularity, and server-side filtering.

It is the companion to relay-best-practices, which handles correctness and architecture - this one picks up once the code is right and still needs to be faster.
