Hi all
I'm new to event loops and am wondering about a couple of things...
Maybe somebody will clarify the questions for me. I'm using ev++ for
implementation, if this is of interest.
I'm implementing a TCP-Socket Server on Linux to which a large number of
embedded devices is connecting and reporting status every 10-60sec.
The current architecture spawns a thread for the server, accepting
connections in an own ev::default_loop.
The server there is 2x ev:signal and 1x ev::io(ev::READ) for accepting
connections.
On accepting the client gets it's own thread with an ev::dynamic_loop.
For the client I'm using 2x ev::io (1x ev::READ, 1x ev::WRITE), 1x
ev::timer, 1x ev::async for stopping.
1. When running an event loop with multiple watchers, per iteration only
one watcher is called - is this intended or is my implementation wrong?
2. Having the ev::timer running, at some point the ev::io watchers stop
working. are the watcher excluding each other?
3. Sometimes the latency is extremly high, when accepting connections. I
can't really find a reason for this. Any hints?
4. Is there any known difference between ev++ and ev I should be caring
about?
I started with this examples as a base for the implementation:

Thanks for your help and patience in advance!
