Hi Woo, IgniteDataStreamer uses per node buffer to make bulk cache updates that shows much better throughput than single updates. Also, IgniteDataStreamer send jobs to remote nodes, to utilize multiple threads on remote nodes.
In multi-node grid IgniteDataStreamer usually shows better results than single updates in from multiple threads.
