+ # Set the acknowledgement window size. If you decrease this
+ # value, the number of acknowlegdments increases. More
+ # acknowledgments means more overhead as conntrackd has to
+ # handle more control messages. On the other hand, if you
+ # increase this value, the resend queue gets more populated.
+ # This results in more overhead in the queue releasing.
+ # The following value is based on some practical experiments
