# AOSPERF06-BP03 Implement HTTP compression
<a name="aosperf06-bp03"></a>

 Reduce request and response payload sizes by enabling GZIP compression. 

 **Level of risk exposed if this best practice is not established:** Low 

 **Desired outcome**: GZIP compression is enabled in the OpenSearch Service domain, reducing the size of data being ingested or requested. 

 **Benefits of establishing this best practice:** Reduce the payload size of requests and responses. 

## Implementation guidance
<a name="implementation-guidance-44"></a>

 In OpenSearch Service domains, GZIP compression can be used to compress HTTP requests and responses. This compression helps reduce document size, lowering bandwidth usage and latency, resulting in improved transfer speeds. 

### Implementation steps
<a name="implementation-steps-28"></a>
+  To use compression, include the following headers in the HTTP requests of your application: 

```
'Accept-Encoding': 'gzip'
```

```
'Content-Encoding': 'gzip'
```
