Hi folks, in a scenario where Wowza works with Live Streaming, receiving RTMP data in an EC2 and converting it to HLS to deliver through a CloudFront distribution, the instance type of this EC2 has a better perfomance if using a G2 instance (which has GPU processing) or isn’t necessary? I have a customer that is complaining about delay in this RTMP to HLS convertion using C3 instances, something about 10 seconds, and I just thought that using G2 instance may be a solution.

Thank you!

Hi,

The delay could also just be to do with HLS playback as it does have inherent latency due to how it buffers a number of chunks before streaming. You can tune this somewhat as [outlined here](https://www.wowza.com/docs/how-to-configure-apple-hls-packetization-cupertinostreaming%28cupertinostreaming%29).
