Response Buffering
If your domain sends many small packets, it may be faster to buffer the file and deliver the full payload all at once (instead of streaming it).

By default, Cloudflare streams traffic data, meaning that each packet is sent as it becomes available. This can improve the delivery of large files. However, this streaming behavior only applies to dynamic traffic; cacheable traffic is buffered and this behavior cannot be changed.
If your domain sends many small packets, however, it might be faster to buffer the file. This approach waits to send the full file until all packets are ready, preventing a client browser from having to re-assemble packets.
To enable Response Buffering in the dashboard:
- Log in to your Cloudflare account ↗ and go to a specific domain.
- Go to Network.
- For Response Buffering, switch the toggle to On.
To enable Response Buffering with the API, send a PATCH request with response_buffering as the setting name in the URI path, and the value parameter set to "on".
