So if the CPUs are split between sockets, would such system generally
perform better or worse with PostgeSQL vs. non-split situation?

Hi,
I plan to commit the patch below to disallow attaching preloaded memory
disks via ioctl. I didn't find anything that would really use this
undocumented feature.

Disallow attaching preloaded memory disks via ioctl.

Your entire email is conjecture, the performance of DragonFly 3.2 is
improved across the board vs 3.0. Not just batch performance,
interactive performance (especially under X11) is also greatly
improved.
