Adding a second ndbd might in some cases improve throughput but will also heighten the=20= risk of swapping and thus heartbeat failures. A machine running only two ndbd processes and nothing else can improve=20= throughput somewhat but still one process on a 2-cpu box will have better real-time=20 characteristics and will sometimes use the entire machine (at high write loads).
