How to reduce smooth latency

I’m testing smooth. But latency comes out about 15 seconds. Is there any way to reduce it further?

@jongwon cho, did you optimize your Smooth settings in the Wowza Application? See https://www.wowza.com/docs/how-to-configure-microsoft-smooth-streaming-packetization-smoothstreaming

A latency of 15 seconds and up is quite common of HTTP-based streaming protocols, especially without further optimization.

I’ve checked it and I made a change But I do not think it’s right.
