The delay of APNs's response is very high(even up to 700s)

Time: 12:00-17:00 UTC everyday

Location: China

The delay of APNs's response: The elapse from sending a notification to APNs Server to receiving a response from it.

Normal delay: 500ms

High delay: 10s-700s

Through put: 50/s


Description:

1. One of my servers' delay is very high (even up to 700 seconds), but another server's delay just slightly increase.

2. Even though the delay is very high, the responses indicate that the most of notifications was post successfully.

3. Restarting my push service will immediately reduce the delay.
