Dave,
That isn't our real application, which does run higher PPS rates:
vpp# show run
Thread 0 vpp_main (lcore 30)
Time 50182.3, average vectors/node 1.00, last 128 main loops 0.00 per node 0.00
vector rates in 6.7225e-1, out 6.8335e-1, drop 5.9782e-3, punt 0.e0
Thread 1 vpp_wk_0 (lcore 12)
At that PPS rate, you don't need two worker threads. The worker threads burn a
bunch of cycles - poll-wait or not - doing next-to-nothing. Try running the
main thread all by itself...

We back-merged the unix poll wait timeout and a 100 usec delay gets us
down to maybe 15%. Just wondering why the change originally.
