Delay when sending over 20 messages

[riderofzion]

Hi,

I am using this function to push messages to my devices and I've got some problems. The first 20 messages are received instantly but after 20, there is delays (like 30 secondes and more).
Device.objects.all().send_message({'id': '{}'.format(msg),})

This problem is not present when I push from "phpfiddle.org" for example.

Thank You
