> Where is an I/O bottleneck if a client tries to perform many
> transactions involving puts and gets in a highly concurrent manner using socket transport to a single server node deployed on powerful multicore computer.
> In what case throughput dramatically decreases (up to 30 times in comparison with running test in single JVM) because everything is delayed by server I/O thread.
> Current workaround for such scenario is using more clients (or servers).
> We should add configuration parameter such maxConnectionsPerClient, allowing client to connect to server using several simultaneous connections decreasing I/O bottleneck.
