      With 1400 r/s you could easily use a static amount of childs, ergo :
      pm = static
      pm.maxchildren = 8
      pm.start      servers = 4

      I’d also set a max amount of requests to avoid memory leaks killing the server:
      pm.max_requests = 16384

        pm = dynamic
        pm.maxchildren = 8
        pm.startservers = 4
        pm.maxspareservers = 4
        pm.max_requests = 16384

        or
