At that point you are > disk-bound > > 37 megabits per second means that there is something wrong. 37Megabytes per second is over 100mbit speeds. 37Megabits per second is roughly 4Megabytes per second, about 40% of 100megabit speeds. Seems a little low, but 37Megabytes per second isn't quite possible over 100megabit.
