They were, after all, written by ordinary mortals like everyone in this discussion. Maybe 256 is too high, perhaps 128 would be more reasonable. 64 seems way too small in any case. Your arguement about latency isn't relevant here. If you were writing a latency-sensitive app, you wouldn't be running tcp. Also, as I understand it, we're setting a minimum on the maximum, not a minimum on the minimum.
