Default is 200 ms. tcp_rwin_credit_pct (Debug) Percentage of receive window that must be buffered before flow control is checked on every received segment.

Default is 1024. tcp_snd_lowat_fraction (Debug) If nonzero, the send buffer low-water mark is the send buffer size divided by this value. Default is 0 (disabled). tcp_status (Read only) Information on all TCP connections. tcp_sth_rcv_hiwat (Debug) If nonzero, the value to set the stream head high-water mark to. Default is 0. tcp_sth_rcv_lowat (Debug) If nonzero, the value to set the stream head low-water mark to.
