Yes you can do Performance testing manually. For this you should open many active sessions of the application and should test it out. It also depends on what type of performance test you want to do. However, in general you can judge the active sessions, number of DB connections open, number of threads running (I have taken JAVA based Web applications as eg), the amount of the CPU time and memory being used by having a performance viewer. You can have IBM Tivoli Performance viewer. It is available for trial version also. Usually the the test is done by deploying the application on the server and accessing the application from multiple client machines and making multiple threads to run. The performance viewer should of course be installed on the server |
