In addition, your iteration of tcpserver/client suffers from the bugs that were fixed in Martin's version, namely misreporting number of connected clients, crashes, xruns when broadcasting, and stale sockets following the crash.


thanks for testing.

good to know that i cannot magically fix all problems in the world.

they are entirely independent from Pd's networking and threading

aye. it's always easy to blame the hardware.

as i understand it, both miller's, my and martin's code (at least the
old one before i forked) just fill up the socket's buffer and trust that
the operating system will distribute the packets in an "ideal" way.
martin's and my approaches try to minimize the impact this has on the Pd
process (with different success - see "xruns")
