Other kernel config help:
  - turn off lock dependency checker, kmecheck, page alloc debug
    basically anything that slows stuff down
  - turn off content group scheduler

Maybe, but i'm not sure (i can't test it):
Disable randomize VA space? On embedded boards it was helping. 
In some case disabling SMP helped, when various SMP locks involved, but maybe 
not for pktgen.

pktgen is a kernel module, and is not affected by randomize VA space.

But of course, disabling SMP must help, as long as your machine needs
one cpu only :)
