## Data throughput by cluster specification

Data throughputs at various cluster specifications supported by Search Engine Service are as follows:

- [When the shard value is 1](/docs/en/ses-spec#Shard%EA%B0%92%EC%9D%B41%EC%9D%B8%EA%B2%BD%EC%9A%B0)
- [When the shard value is 3](/docs/en/ses-spec#Shard%EA%B0%92%EC%9D%B43%EC%9D%B8%EA%B2%BD%EC%9A%B0)
- Increasing the shard value may result in better performance.

              Caution

              

The cluster's performance may vary according to its shard value, replica value, volume of imported documents, and storage usage. NAVER Cloud Platform is not responsible for malfunctions caused by the user's configuration updates.

              Note

              

- Performances were evaluated using Rally, the benchmark script from Elasticsearch.
- The provided data is for reference only. Make sure to perform a test yourself before on-the-ground implementations.
