# Case studies
These are case studies of performance optimization in Kibana plugins, based on real-world examples.
- [Case Study - Async too early](https://docs-v3-preview.elastic.dev/elastic/kibana/tree/main/extend/key-concepts/performance/case-studies/case-study-async-too-early)
- [Case Study - Top level imports](https://docs-v3-preview.elastic.dev/elastic/kibana/tree/main/extend/key-concepts/performance/case-studies/case-study-top-level-imports)
- [Case Study - Uncommon code in common](https://docs-v3-preview.elastic.dev/elastic/kibana/tree/main/extend/key-concepts/performance/case-studies/case-study-uncommon-code-in-common)

<warning>
  The purpose of these case studies is to provide examples of performance optimization, but not to call out individual teams or plugins.  Every plugin author should study these and other examples to ensure their plugins are also optimized.
