Method: Capp#timeout=

Defined in:
ext/capp/capp.c

#timeout=(milliseconds) ⇒ Object

Sets the maximum amount of time in milliseconds that will elapse between receiving a packet and yielding it to #loop.

Reducing the timeout will increase responsiveness as pcap_loop(3) must “check in” more frequently while increasing the timeout will reduce responsiveness.

Setting the timeout too low may increase GVL contention when many packets are arriving at once as #loop will be waking up frequently to service captured packets.
