I'm timing the latency for an application (a screensaver in this case)
to handle a mouse click. I take a timestamp in the mouse driver
(appletouch, usb) and another timestamp when the screensaver handles the
event. For the appletouch driver I get a latency of ~83 ms, and the usb
mouse is ~57 ms, which seems like madness. Keyboard clicks are ~5.7 ms
which are more on the order of what I expected for the mouse clicks.
What's the expected latency of mouse clicks?
