I captured the script for a web application and then ran a test using the same script.The task was running for hours and only a single chart was generated for the active users and nothing else.
Why does it takes too long(I left teh office when it was in running state and came back after around 15 hrs and it was still running with no progress on the number of charts.

Does it depend on the length of the script?
I would be thankful for the reply.
