I agree.

I agree that leaving it enabled helps to find bugs, however I'm not
happy with the round trip time degradation.

When using auto corking with iSCSI the round trip time at least increases by
factor 25 probably more. Other protocols are very likely also effected.

Hello Eric,
Disable auto corking by default
We should let auto corking on during 3.14 development cycle so that we
can fix the bugs, and thing of some optimizations.
I agree that leaving it enabled helps to find bugs, however I'm not
happy with the round trip time degradation.

Hello Eric,
Sure, but if we put this flag to zero, nobody will ever use it and
find any bug.
I agree.
If we can add the MSG_MORE at the right place, your workload might gain
~20% exec time, and maybe 30% better efficiency, since you'll divide by
2 the total number of network segments.
