The first thing to understand is that QuickBits does not speed up every operation of your handheld equally. For example, text drawing on some devices is over 6 times faster. On the other hand, database operations may be only 1.1 times faster. The amount of performance improvement bestowed on a given application is completely dependent on the mix of operations performed by that application. On top of this is the issue of one's perception of performance.
Different people have different sensitivities to application speed.
One person will say a given application is unresponsive while another says it is just fine. The qualitative measurement, how much performance improvement you perceive in the Palm applications you use, can't be measured by QuickBits. This is why we provide a trial version. Due to the nature of the timers being used there will be slight variations from run to run and from device to device. However, large variations indicate something is impacting the performance of your device.
