Hello,  
we send our Streams ( Akamai-Stream Targets -\> HLS Push ) to the Akamai Network. I have read this Wowza Article -\> [https://www.wowza.com/docs/how-to-stream-to-akamai](https://www.wowza.com/docs/how-to-stream-to-akamai)

There is a Notification:  
" \* (Wowza Streaming Engine 4.7.5.01 and earlier) If your Akamai endpoint will ingest an HLS stream, we recommend that you use the default **cupertinoChunkDurationTarget** value of **10000**. Lower chunk durations may introduce throughput issues on the Akamai network."

Is this also a Problem with the newest Wowza Version 4.8.5? I ask, because we have adjusted 6 Seconds for the HLS-Chunk Size.
