-----------------------------------------
Summary: I/O bottleneck on server/client cluster configuration.
Key: IGNITE-3220
URL: https://issues.apache.org/jira/browse/IGNITE-3220
Project: Ignite
Issue Type: Bug
Components: clients
Reporter: Alexei Scherbakov
Priority: Minor
Fix For: 1.7
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.
