Can I ask (please keep answers low tech) management freindly when you are migrating to a new thin client environment (3000 users!) what types of testing should be done to ensure the thin client infrastructure can perform adequately when all users are logged in and using the system,
I just see it must be difficult to simulate the same amount of usage unless you ask all 3000 of your users to access the test system, which isnt really practical.
What sort of stress testing do you perform and how on test environments to see if they are going to be able to do the job? Or what sort of watermarks/thresholds are you looking for that this is not going to take the strain?
