Average response times application server. This graph shows the average response time of the application server in milliseconds for a given number of concurrent users. These users have been simulated using Apache JMeter. Between 0 and 25 concurrent users, the average response time hardly increases. With more than 25 users, the average response time starts to increase. This is caused by a queue of requests which increases. This indicates the system is capable of handling 25 concurrent users.
