Plz help me to find out the answers to the following questions.
1-Can CPU performance be measured by Load Runner or is it only for client/server applications? for eg If i open several task windows can i measure the cpu time and its performance.
2- The "Elapsed Time" is the major ingredient in all the plotted graphs. Most of the graphs are plotted against "elapsed time" on x-axis. What is the significance of "elapsed time"?
3- Is 3 tier architecture supported by LoadRunner?
4- What are input/output delays and database locking? How does LR find if the performance has degraded due to these factors?
Thanx in advanced.
Interview questions again, I guess.
1, 3 and 4 are LoadRunenr related, but the dictionary would give you the answer to #2!
These were the questions asked by one of our seniors who themselves are new to Load Runner. I myself have started learning LR and new to it so not sure about the whole process and working.
About Q2 - Yes I know the meaning of it well but was still unsure why all the graphs are plotted against it. If you could guide me further on this it will be great.
Looking forward for your expert guidance and assistance.
Most of these queries could be answered by going through the help files which comes with LR.

3 Yes (if you mean testing of a 3-tier application)
4 Speak to a DBA
Well, regarding question 2. If you had a bunch of data consisting of response times, what would YOU plot them against?
Thanx a lot for the answers but can someone explain how to go for CPU performance measurement by Load runner.
You will need to add measurements (and identify machines) to the relevant monitor that contains CPU usage AND that you have a license for.
e.g. Windows Resources, MS IIS, etc...
This is in the manual. RTFM.
Thanx for ur reply.
well i am looking for a bit of detail into the CPU performance query ....
it would be nice if someone could write some detail.
lets take the example of a client machine, and what if we need to measure the CPU performance during a specific operation e.g. graph generation by multiple users at a time?
