I take back my last post. It was real world oriented, where the time spent between gates is the most important figure the airline wants to know. Time is money to them. I typically in an airliner park it right on 30 knots for the taxi, with about 5-10 for turns. Slower for the 727 and 757 so the passengers in back and front don't get slung around. In the small turboprops, you could pull a turn at 20 or so, though it would be extremely uncomfortable and not too good on the tires. Brake usage is a big thing during taxiing too, both for takeoff and landing. Brake temperatures are a major thing we airline pilots monitor. Because, if the fecal matter were to impact the spinning blades and we were to have to do a rejected takeoff, you want maximum brake performance to make sure you can stop on the runway. On landing, the temperatures are just something you keep an eye on during the roll...not anything you give thought to just a glancing check.
edit: oh and Nexus, I noticed you spoke of cabin noise as a reason for not going all that fast while taxiing. If you have ever been to Dallas/Fort Worth International Airport in Dallas, Texas (I am based out of there) you would see that there are bridges that allow planes to taxi over the highway that cuts the airport in half. Well apparently the guy that designed those there bridges wasn't payign much attention, and there is a very very noticable bump at both ends. When I was just hired several years ago and was still a junior first officer with basically no experience, I hit that thing doing about 25 knots in a little Embraer 120 turboprop and it shook horribly and was incredible freakin' loud. Looking back, it's funny now, but it didn't do much to cheer up the passengers or my captain.
