Describe the problem that you experienced

The Performance Optimization guide has not been updated in a long time, and the video referenced in the guide was created around five years ago.

We should review and update the guide to ensure the information reflects current best practices and modern performance optimization techniques. This would be particularly valuable because up-to-date, comprehensive information on this topic is still relatively limited online.
