# Elasticsearch performance optimizations
Elasticsearch's default settings provide a good out-of-box experience for basic operations like full text search, highlighting, aggregations, and indexing.
However, there are a number of optimizations you can make to improve performance for your use case. This section includes both deployment-level configuration suggestions and usage-level guidance to optimize the performance of your cluster.
Use the following topics to explore relevant strategies:
- [General recommendations](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/5385/deploy-manage/production-guidance/general-recommendations)
- [Tune for indexing speed](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/5385/deploy-manage/production-guidance/optimize-performance/indexing-speed)
- [Tune for search speed](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/5385/deploy-manage/production-guidance/optimize-performance/search-speed)
- [Tune approximate kNN search](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/5385/deploy-manage/production-guidance/optimize-performance/approximate-knn-search)
- [Tune for disk usage](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/5385/deploy-manage/production-guidance/optimize-performance/disk-usage)
- [Size your shards](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/5385/deploy-manage/production-guidance/optimize-performance/size-shards)

<note>
  Many Elasticsearch options come with different performance considerations and trade-offs. The best way to determine the optimal configuration for your use case is through [testing with your own data and queries](https://www.elastic.co/elasticon/conf/2016/sf/quantitative-cluster-sizing).
