Oracle Exalogic Elastic Cloud Software (EECS) includes performance optimizations for SPARC SuperCluster T4-4 to improve input/output, thread management, and request handling efficiency.
Additional optimizations include reduced buffer copies, which result in more efficient input/output. Finally, session replication performance and CPU utilization is improved through lazy deserialization, which avoids performing extra work on every session update that is only necessary when a server fails.
WebLogic Server clusters can be configured with cluster-wide optimizations that further improve server-to-server communication. The first optimization enables multiple replication channels, which improve network throughput among WebLogic Server cluster nodes. The second cluster optimization enables InfiniBand support for Sockets Direct Protocol, which reduces CPU utilization as network traffic bypasses the TCP stack.
