Test Method
Prepare 100 users for the test. Users who selected randomly perform the following scenario repeatedly for 5 minutes.
Measure process time (Using Jmeter), CPU utilization, Memory load (using vmstat)
Access to the servers in simultaneous number (5, 10, 20, 50, 70, 100, 150) of sessions.
* In case of 150 sessions, prepare 150 users.
* Prepare 100 messages per user (95 messages without attachments, Size: 10KB. 5 messages with attachment, Size: 885KB)
Scenario
- Login (Click Login button and wait until all the messages displayed in the screen)
- Receive Messages (Click Receive button and wait until Receive Dialog disappears)
