HOW would you suggest that a user try to concurrently test both applications in so-called 'real time' and with all parameters equal ?
What would you suggest regarding the minimum time such an experiment should have as its course ?
What 'test criteria' would you suggest in order to 'normalize' the test... i.e. what file(s) to be chosen for Search, Download and Upload ?
The files must be the same for both 'clients'.
The connections must be absolutely equal.
The system resources available must be identical.
and, errr, a long list of other thingies that gotta be the same...



At best, the resultant can only be an extrapolation...

Engineers know that extrapolation is a really nifty word that actually means to bulls*** oneself !!!
Scientists have even funnier definitions for it...
