This topic describes the effect of mediating messages concurrently at a selected destination.
Several messages may be mediated concurrently, to achieve maximum throughput for a selected mediated destination.
The number of mediations that can be run concurrently against any single destination is limited by the maximum thread pool size.
You can specify that a mediation operates concurrently by setting the Allow Concurrent mediation property to True, using the administrative console. If message ordering is important, do not allow concurrent mediations. By default (Allow Concurrent mediation is set to False), a single message is mediated at a time.
