Adobe Flash Media Server 4.5 * Configuring performance features
Configure the server to deliver live media
The following three configuration settings impact scale and latency for live media delivery:
Note: You can’t send aggregate messages and combine audio samples in the same application.To configure the server to deliver live media, choose your use case:
- Large Scale Broadcast (scale is more important than latency)
- In this use case, you want to reach as many people as possible and are willing to allow some latency. You may also want to keep costs down while still reaching as many people as possible. Send large aggregate messages and configure large stream chunk sizes.
- Large Scale Broadcast (low latency is more important than scale)
- In this use case, you want to keep latency as low as possible while reaching as many people as possible. You are willing to trade some scale for decreased latency. Send smaller aggregate messages. Or, combine audio samples and do not send aggregate messages.
- Interactive (lowest latency)
- Interactive applications require very low latency. Do not send aggregate messages. For the lowest latency, do not combine audio samples.
If data latency is your concern, combine audio samples. Combining audio samples introduces audio latency but doesn’t affect the rest of the stream. Aggregating messages introduces latency to the whole stream.
Interactive applications are the most difficult to scale and require more hardware than the large scale broadcast use cases.
