I'm writing an application that requires low latency. I know that
there is this special bit flag that can be set for a TCP packet called
Push which forces TCP to immediately send the data out without waiting
for its buffer to fill up first.
Looking at data captures from CFStream write operations, it seems that
sometimes the Push flag is set while sometimes it is not. How does
CFStream determine whether the flag is to be set or not and how can I
force it to always flag my data to be pushed?
Side question: There is no CFStream for listening right? I have to use
sockets for that?
[To Quinn regarding my previous question: Thank you, your
clarifications solved all the uncertainties I had!]
