Tune performance
To improve performance, consider certain items such as operating system and network tuning, planning for network ports, Java™ Virtual Machine (JVM) tuning for WebSphere eXtreme Scale settings, configuring failover, and other tuning topics.
- Plan for network ports
WebSphere eXtreme Scale is a distributed cache that requires opening ports to communicate with the ORB and Transmission Control Protocol (TCP) stack among Java Virtual Machines and other machines. You should plan and control the ports, especially in a firewall environment such as when you are using a catalog service and containers on multiple ports.- Operating systems and network tuning
Network tuning can reduce Transmission Control Protocol (TCP) stack delay by changing connection settings and can improve throughput by changing TCP buffers.- ORB properties and file descriptor settings
Tuning considerations include ORB properties and file descriptor settings.- JVM tuning for WebSphere eXtreme Scale
Java virtual machine (JVM) tuning can yield a significant improvement in the deployment of WebSphere eXtreme Scale.- Configure failover detection
You can configure the amount of time between system checks for failed servers with the heartbeat interval setting.
