Adobe Forums: FMS server buffer delay 5-6 sec live stream ?

To reduce the delay you can try disabling aggregate messages.

You need to set Streams/EnableAggMsgs in Server.xml and Client/AggregateMessages in Application.xml to false.

See more about Aggregate messages here : http://help.adobe.com/en_US/flashmediaserver/configadmin/WS5b3ccc516d4 fbf351e63e3d119f2925e64-7ff0.html#WS5b3ccc516d4fbf351e63e3d119f2925e64 -7feb

 

Hope this helps.
