Even with this trace flag enabled the log reader always waits for the sync secondaries. The log reader will not go beyond the min ack of the sync secondaries. This trace flag applies to the instance of [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)], not just an availability group, an availability database, or a log reader instance. Takes effect immediately without a restart. This trace flag can be activated ahead of time or when an async secondary fails.

This feature is enabled by default on asynchronous availability groups in order to optimize network bandwidth.
