When the reader sends a notification message out over the network, it needs an
open TCP socket to do so. Opening and closing a socket entails some processor
and network overhead, and if the notifications are coming out of the reader
rapidly, this overhead can become a burden that hinders reader responsiveness.
The NotifyKeepAliveTime attribute sets the amount of time (in seconds) that the
reader will keep this socket open. For rapid notifications, it may be advantageous
for the reader to hold the socket open continuously. You do this by setting
NotifyKeepAliveTime to some value greater than the expected time between
notifications.
