I see that the tcp_recv_hiwat has finally been increased from 48K. Yippee!
At http://bugs.opensolaris.org/view_bug.do?bug_id=5031055, it says: If you are going to raise them, make it something respectable for this millenia. The issue happens if you make them exactly 64K. There are some silly network devices that seem to barf when they are right at this value. That means that you should probably make them 64000 (at least one MTU smaller than 64K in any case). Of course, on Linux boxen; I believe they are set to right around 64K - but they also support RFC1323 for window scaling when you want larger than 64K. I see the value was raised to 128000 instead of 128K. Can anyone clue me in on what problem is being avoided by not setting it to a power of 2?
