Another scenario. Consider application that takes few seconds to process
single request. In non-multiplexing mode we’re still limited to roughly
32K
simultaneous requests even though we could install enough backend
servers to
handle 64K such requests per second.
Now, imagine we can use FastCGI connection multiplexing. It could be
just
single connection per backend. And, again, we are able to serve roughly
twice as many requests per second with the same hardware but little tiny
feature called FastCGI connection multiplexing.
