Common application performance data description

1. Number of concurrent users (NCU)

Number of concurrent users-the number of concurrent user connections observed by the system at the specified time.

2. Request per second (RPS)

Number of requests processed per second-indicates the average number of user transaction requests that can be processed by the server per second.

Response time: the length of time from the time the customer sends a transaction request to the last byte that receives the processing result.
