# Performance Best Practices

> Where to find Canton application performance guidance — moved to the consolidated Performance Optimization deep-dive.

The detailed performance guidance — on-ledger vs off-ledger trade-offs, contract design for performance, PQS query optimization, parallel command submission, traffic management, and the worked example for reducing contention — now lives with the rest of the performance material in [Performance Optimization](/appdev/deep-dives/performance-optimization).

For diagnosing performance issues in a running validator, see also:

* [Performance Issues](/appdev/troubleshooting#performance-issues-2) and [Contention](/appdev/troubleshooting#contention) in the troubleshooting cheat sheet.
