weather it can handle peak usage periods

Q2. What is Performance testing? Ans. Timing for
both read and update transactions should be
gathered to determine whether system functions
are being performed in an acceptable timeframe.
This should be done standalone and then in a
multi user environment to determine the effect of
multiple transactions on the timing of a single
transaction.

can not be any generic value for Vuser.

Q8.Why do you create parameter? Ans. To create a
parameter you will replace the hard coded value
within the script and replace it with a
parameter.  This allows a single Vuser to be run
many times, and to use different data on each
run. It helps in stimulating more real life
server demand as it prevents server from caching
results.

Q9.What is Correlation? Ans. Correlation is used
to obtain data which is unique for each run of
your test script (ex session ids). While
recording, these dynamic values are hard-coded in
your script causing the script to fail during
playback. Correlation is a technique where
dynamic values are not hard-coded in your script
but are extracted at run-time to avoid failure.
