The response time metric for a business transaction provides performance information about the transaction. However, in asynchronous applications, it may not indicate everything.

Consider a method that spawns other threads, possibly on other tiers, and then immediately returns control to the calling thread. The return of control stops the clock on the transaction in terms of measuring response time, however the logical processing for the transaction continues.

End-to-end latency metrics can reflect the response times for such asynchronous transactions.
