I'm hoping there is a good explanation for the behavior I'm seeing. I
have a relatively simple client application which connects to a server
and subscribes to a feed. The socket on the client is then associated
with an io watcher running in the main event loop, so that messages are
received and processed in a non-blocking way. The problem I'm
experiencing is that it takes anywhere from 30 seconds to a minute for
the watcher to be triggered for the first time, even though the server
is emitting a message every couple of seconds. Once it has been
triggered the first time, it then starts to respond to the messages as
it is supposed to. Neither the size of the messages nor the frequency
appears to have much influence on this delay.
I have confirmed with tcpdump that the server does in fact send every
message. Also, if I take the recv() logic out of the callback function
associated with the watcher and run it synchronously, everything works
properly.
I'm at a loss to explain the observed behavior, and would appreciate
either an explanation, or follow-up questions that would allow us to get
to the cause of this.
