These are the 2 terms which is often used in Performance Testing...
Simultaneous users are the users who have a valid session in the server. Each of the users would be performing different actions like one doing login , other viewing the reports, etc.
Concurrent users are the users who have a valid session in the server & they are performing the same operation at any point of time. All the concurrent users would perform login, reports download, etc at the same point of time.
Example:
Hence for a web site, the number of simultaneous users would be always greater than the concurrent users. For example; a banking web site has the workload of about 30000 simultaneous users & 5000 concurrent users.
Knowing the correct figures of simultaneous & concurrent users is very vital in order to perform performance testing of an application.
