次のオプションも設定しました。
echo 3000 > /proc/sys/net/core/netdev_max_backlog
echo 3000 > /proc/sys/net/core/somaxconn
そう、
1) 最初の 3000 件のリクエストを超高速で作成します。ab と uwsgi requests ログに進行状況が表示されます -
[pid: 5056|app: 0|req: 518/4997] 80.114.157.139 () {30 vars in 378 bytes} [Thu Mar 21 12:37:31 2013] GET /about/ => generated 1881 bytes in 4 msecs (HTTP/1.0 200) 3 headers in 105 bytes (1 switches on core 0)

壊れたパイプやワーカーのリスポーンはありません。
2) 次のリクエストの実行が非常に遅いか、タイムアウトがあります。一部のバッファがいっぱいになったようで、空になる前に待っています。
3) 一部のバッファが空になります。
4) 約 500 件のリクエストが超高速で処理されます。
5) タイムアウト。
