quad encoder read speed

This is as much a programming problem as it is a mechanical issue I guess.
A few of us are working with quad encoders at the moment and I'm just wondering about ideas how to overcome a problem I've encountered using some.
I'm using interrupt on change to count encoder ticks and also reading a 16 bit timer for the interval between ticks on each motor.
