>Also I would load the App with 2 more users and when the performance drags down, run coverage profiler on the code that displays the degraded performance the most and that should give you a good idea about the bottlenecks that you need to tackle.

IF a common function is used for opening and closing tables in your up add measuring there for a first try togehther with a time-measuring enabled log. Might explain a lot of the timing difference with less work and no problem of coverage distorting the actual times.
