The equivalent TCP raw tunings for Solaris based OS's ndd -set /dev/tcp tcp_xmit_hiwat 1048576 ndd -set /dev/tcp tcp_recv_hiwat 1048576 ndd -set /dev/tcp tcp_max_buf 4194304
Those are the raw tunables and if you run get on those you'll see that they are different than what's in ipadm. One is just buffers, but these are the sliding window parameters. How big is your latency? Agreed that 1Mb seems like plenty even for east/west coast high-bandwidth WAN. You certainly wouldn't need to go about 4MB for that.
