Hello! It is hard to say what is the limiting factor here. Yes there's a lot of threads on YCSB side, but still a single one on Ignite side. And it's sitting on Communication write.
Can you try doing the following: supplying custom TcpCommunicationSpi as ignite's communicationSpi with .setUsePairedConnections(true).setConnectionsPerNode(4) on all nodes? I wonder if we'll see more parallelism that way.
