I upgraded client/server machines and could get 300/sec (noproxy) with
Poly-1.3.9. Since I didn't need, I didn't test higher rate.

warmup phase console output! warmup load_factor_beg was 0.1 so It was
I disabled delayed acks in linux using patches reachable from:
I could get 300/sec with Poly-2.2.9 no-proxy test.
But I got some errors by polyclt:
