Re: [bug-myserver] task #9307: Propose to improve GNU MyServer Throughput and Reliability

Hi Alexandru,

today I finally had the opportunity to play a bit with SCTP.  From this
first experience, it seems there are a lot of work to do before we can
seriously use it.  Beside `sendfile' that is not supported (yet?), I
couldn't read directly from a stream in the One-To-Many style and it is
a big limit, sctp_recvmsg doesn't allow to choose from which stream
read, we can't assume the data sent by the client can fit only in a
packet: imagine for example a POST or a PUT request, after the HTTP
header there can be a huge amount of data so there is need of a
multiplexer to dispatch it correctly, the same for FTP transfers.  All
these problems, IMHO, makes the SCTP usage slower than TCP.
Until we will not find an answer to these questions, what do you think
about using SCTP as in the One-To-One model?  At least we can take
advantage of the multihoming feature without loose the functionalities
we have with TCP.  I think this will not take more than 20 lines of
code.

Regards,
Giuseppe
