X-Sendfile

The Send HTTP middleware and the X-Sendfile HTTP response headers are used to stream large files using the RoadRunner. While the file is being streamed with the help of the RoadRunner, the PHP worker may be accepting the next request.

Original issue: link The middleware reads the file in 10MB chunks. For example, for the 5Gb file, only 10MB of RSS is used. If the file is smaller than 10MB, the middleware adjusts the buffer to fit the file size.
