GCM: how to avoid throttling

Question

My android system needs to send frequent updates to an app for tablet (a kiosk always connected to wifi and power plug).

Answer 1

Maybe setting time_to_live to 0.

From http://developer.android.com/google/gcm/adv.html:

"Another advantage of specifying the expiration date for a message is that GCM will never throttle messages with a time_to_live value of 0 seconds. In other words, GCM will guarantee best effort for messages that must be delivered "now or never." Keep in mind that a time_to_live value of 0 means messages that can't be delivered immediately will be discarded. However, because such messages are never stored, this provides the best latency for sending notifications."
