Hi, what happened to the Solaris 10 TCP fusion tunables in
Nevada/OpenSolaris? The variable I can find via mdb on Solaris 10,
/tcp_fusion_rcv_unread_min/, is not in build 134. A quick search of the
source shows a reference to /do_tcp_fusion/ only.
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/inet/tcp/tcp_fusion.c
Does TCP fusion now only use the SND/RCV buffer sizes for flow control?
Did the counter of outstanding writes without a read get removed
altogether? Essentially the equivalent of setting
/tcp_fusion_rcv_unread_min/ to 0?
That's correct.
Is there a specific CR reflecting this change?
Yup.
6826274 remove synchronous streams from tcp
PS. I also see that do_tcp_direct_sockfs is no longer there.
That was also removed as part of 6826274.
