Just had a big issue with sockets. Make sure your DNS is set up
correctly or you are going to have a delay in opening and closing of
sockets. This did not seem to be an issue in AIX just Windows.

In my experience its best to use non-blocking sockets..
It's can be a bit of a pain depending on the situation, but with some
careful wait until x unless received y bytes type loops you can cater
for pretty much any scenario.. In the scenarios where I have control
over both sides of the
Aren't simple protocols, even custom ones, great! ;) I almost always
write code using non-blocking functions so that there is true control. You
gain more control over the data and you can build more responsive
applications since you're not letting the network subsystem control the flow
of your
For anyone currently using Message Queues - please switch to sockets - I
speak from personal experience that the performance and throughput gains
were huge.

John,
Be aware that sockets are a stream based protocol and not a message
based protocol. When you send data to a socket it may arrive in one or
more pieces (packets). On a LAN this may never occur, but over a WAN or
the internet your data packets will almost surely be broken up into
smaller
Kevin, aren't you describing UDP communication, not TCP? Packets can be
fragged and move through any number of different channels w/ UDP, but
they're reassembled as a part of being received through TCP. If you sent a
1024 packet over UDP I would expect exactly what you've stated. Send a 1024
The issue is that if you send a 1024 byte message through a TCP socket, you
may eventually get 1024 bytes out the other end, but you may not get them
all at once. The message may be broken up into lots of pieces, i.e. if you
do a read(), you may get 1024 bytes, or you may get a lot less, and have

I will respond to your message when I return.
