Is there any performance difference between udev and evdev in xorg?

If you don't need them (e.g. because this is desktop system without
fancy input devices), you'd better off with disabling both of them
altogether and use good old traditional way, that is, simply install
xf86-input-{keyboard,mouse} and let X.org handle those peripherals.

Yes, you would still be able to plug and unplug your USB mice and
they will be detected and working as expected.

TL;DR: DEVD/UDEV support is overrated and usually not needed at all.
