Record the scripts with LoadRunner,and run the scripts with the same settings, why are the results different? What will affect the result?
What do you mean?
You amend the Recording Options as required before recording the script.
You amend the Runtime Settings as required before running the script.
If the results you have are different (the script replay is failing?) then the issue most likely lies with correlation. Substantial coverage of this topic is available in the manual.
I means: the script replays successfully, and the Recording Options and Runtime Settings are the same, but the result (transaction response time) is different!
Differing initial conditions.
Document the changes in the environment between run one and run "N" and you will likely identify the reason for the performance deviation.
