If you delay the acks more than 2 packets you will see packet
loss less quickly. Acks are the only feedback mechanism a senders can
use to quickly respond to loss conditions. 2 is a compromise between
wasting net bandwidth, taking advantage of the possibility that the
ACK could piggyback with real data, and having reasonable reaction
time to loss events.
