-tcp_max_ssthresh - INTEGER
-       Limited Slow-Start for TCP with large congestion windows (cwnd) defined in
-       RFC3742. Limited slow-start is a mechanism to limit growth of the cwnd
-       on the region where cwnd is larger than tcp_max_ssthresh. TCP increases cwnd
-       by at most tcp_max_ssthresh segments, and by at least tcp_max_ssthresh/2
-       segments per RTT when the cwnd is above tcp_max_ssthresh.
-       If TCP connection increased cwnd to thousands (or tens of thousands) segments,
-       and thousands of packets were being dropped during slow-start, you can set
-       tcp_max_ssthresh to improve performance for new TCP connection.
-       Default: 0 (off)

 tcp_max_syn_backlog - INTEGER
        Maximal number of remembered connection requests, which have not
        received an acknowledgment from connecting client.
