My speed setting depends on my layer height... through lots of trials I have come to a relative conclusion that my speed should be like the following:
Layer Height 0.1 - speed 15mm/sec or below
Layer Height 0.2 - speed 25mm/sec or below
Layer Height 0.3 - speed 35mm/sec or below
ABS/PLA same speed setting
Hope that helps :)
