ok. To get back to your original question: > Currently Lustre network is bond0.

Since you can reproduce the perf drop with LST, you don't need to change the filesystem configuration to test the different lnet configs. I would just umount the filesystem, reconfigure lnet by changing the modprobe file and run LST.
