Subject Re: Diff between "Uniform Random Timer" and "Constant Timer"
Date Tue, 09 Aug 2011 12:36:35 GMT
Good, point, but then the original requirements are rather insane:
"Performance Testing Requirement is to create different Thread Groups
for different functionalities and execute these thread groups with one
user for 12 hrs."

I'm not sure about the practical use either but, well, there it is.

Of course "one user" is ambiguous and may well mean "using a single set
of login credentials" and say nothing about thread concurrency. If
that's indeed the case, the OP should take especial note of the points
just raised.
