Travis Gummels 2017-01-17 19:00:29 UTC Summary Serious Performance regression with NATed IPoIB connected mode [LLNL 7.4 Bug] Serious Performance regression with NATed IPoIB connected mode
Jonathan Toppins 2017-02-03 19:05:20 UTC Doc Text Cause:
A change to the GSO control block
causes a conflict with the IPoIB
control block resulting in IPoIB
address information that is cached
in the control block to get overwritten.

Consequence:
The overwriting of the cached data
results in a significant performance
degradation on IPoIB fabrics.

Fix:
Move the IPoIB address information
to another section of the socket buffer
preventing the overwrite.

Result:
Restoration of original performance.
