Performance center is part of loadrunner... Your question
should be difference between controller and performance
center?

Ans) Controller- exe based.. should be installed in the
machine

Performance center- Web based.. It can be used globally by
booking time slots

Answer / ravichandra

What ever mohansundar said above is exaclty correct.
I will few more points to the above to make more clear.

Diff1:
Performance center(PC) is web based application which can be accessed any one from any where in the globe by simplay entering URL and credentials.

where as controller is native application which needs to be installed on your local machine.

Diff2:
PC is enterprise application.
where enterprises have multiple applications located in different places we can monitor all applications from single place and maintain centrally located database where anyone from any where can access and make updates

Since controller is a native application only one can access and make updates

Diff3:
PC can effectively use by booking time slots(reduce costs) which is not possible in controller,Every one has to buy license from HP.
Installing LoadRunner on 'x' performance testers PC's will be a lot more expensive than sharing it as a resource between them through Performance Center.



Diff4:
The HP Performance Center software can be centrally administrated.
Which is not possible in controller

)Example of web_submit_form is the regestration form which u have to fill while creating a mail_Id Example of web_submit_data is the login page contains the fields like user name & PWD. Is this correct answer for diff btn web_submit_form&web_submit_data and their examples.
