Round Trip performance is mostly defined by the response time (round trip time) of a user transaction opened in a web browser. The user experience is defined by a combination of components that are required to present this transaction to the user.
Round-trip time (RTT) is the total time taken for a packet sent A to reach a destination B and then for a response to sent back by B to reach A. In other words, the round-trip time is the sum of the one-way delays from A to B and from B to A, and of the time it takes B to formulate the response to the original packet.
Round trip is a combination of the following measures:
- Database performance: A combined score based on 5 specific performance indicator reported with a 5 minute interval.
- Enterprise Server processing performance: Defined by a number of outstanding requests that should remain below a critical maximum (10 results in a warning, 20 results in a request).
- Web server performance: Only operating system counters will be reported on the Web Servers.
- Round trip performance measured between a user session and the data centre for representative applications on at least a daily basis.
