Answer / srinivas
If you mean, how much scaled down version of production to
be used for performance test environment simulation:
Number of unique users should be the same. I mean if prod-
site gets hit from x uniquie user-ids concurrently at peak
load, better to simulate same no. of users in your tests(
which generally is not done so can go with atleast 75%).
Because no. of users do determine the connection holding
ability of the servers.
In case of TPS, simulate according to the scalling factor u
have used to architect your test env against the prod.
Here i mean, if tps rating of prod-h/w divided by tps
rating of test-h/w is 1.5, then you can try to load your
test env with full tps load capacity just to ensure test
systems burn bfore prod-systems burn(if they were to burn
in case of bad app).

Dear Gurus, I have an interview in a company in Chicago and my latest project has the following description can anyone let me know what would be the QUESTIONS that can be asked from the following. Thanks,  Developed test cases and test plans and analyzed the test results using for LoadRunner.  Involved in Load/Performance Testing  Created LoadRunner Scenarios and Scheduled the Virtual user to generate realistic load on the server using LoadRunner.  Created and implemented Performance tests using Mercury Interactive LoadRunner.  Enhancing the scripts using Generator and performed Parameterization and Correlation to meet the requirements.  Involved in performing load and stress test on the application and server by configuring LoadRunner to simulate hundreds of virtual users and provided key metrics to the management.  Configured and Using Performance Monitor to monitor and analyze the performance of the server by generating various reports for CPU utilization, Memory Usage, load average etc.  Involved in conducting stress test and volume test against the application using LoadRunner.  Used Quality Centre to invoke the scripts and initially performed the baseline testing and organized all the scripts systematically and generated reports.  Performed regression testing for every modification in the application using Win Runner.  Involved in performance testing of server’s load and scalability by creating multiple Virtual Users by using Load Runner Virtual User Generator component.  Created detailed test status reports, performance capacity reports and graphical charts for upper management using Load Runner analysis component.  Involved in parameterization of script using VuGen in Load Runner. Please.........
What are the process for developing a vuser script?
Why we insert the rendezvous point while running the scenario?
While the script is running we find some values that may need to be correlated? Is it possible to do manual correlation for those values?
What is RDR files in Load runner? What is Scenario Configuration in Load runner
how much memory will allocate for 1 vuser?
How do you identify which values need to be correlated in the script? Give an example.
Where you insert the rendezvous point?
What is mutation testing?
We use pacing to have interval between two iteration of script. Why?
What are all the reasons to use the server resources monitor?
What is the differences between parameterization and correlation ?
