This has a negative impact on performance, +but is necessary in order to provide a common interface +for both HTTP/1.1 and HTTP/2 (as well as future HTTP +versions). + +It is still possible to use a single process per +connection, and avoid the creation of additional +processes for each request, by implementing a +stream handler to process the requests. This can +be done for all requests, or just for a single +endpoint depending on the application's needs. + +Stream handlers provide an asynchronous interface +and must not block, so the implementation will +be very different from normal Cowboy handlers, +but the performance gains are important enough +to justify it in some cases. |
