21-4 Oracle Fusion Middleware Performance and Tuning Guide 100. This can be increased to a desired value provided there is sufficient memory for runtime data processing for large number of proxy services. This property value can be set in the setDomainEnv.sh file as an extra java argument as follows: -Dcom.bea.wli.sb.pipeline.RouterRuntimeCache.size={size} Example: EXTRA_JAVA_PROPERTIES=-Dcom.bea.wli.sb.pipeline.RouterRuntimeCache.size=3000 {EXTRA_JAVA_PROPERTIES}

21.4 Transport Tuning WLS and OSB

Latency and throughput of poller based transports depends on the frequency with which a source is polled and the number of files and messages read per polling sweep. The following are the main transport configurations to tune:

21.4.1 Polling Interval

Consider using a smaller polling interval for high throughput scenarios where the message size is not very large and the CPU is not saturated. The primary polling interval defaults are listed below with links to additional information:

21.4.2 Read Limit

The read limit determines the number of files or messages that are read per polling sweep. This defaults to 10 for the File and FTP transports. It can be set to 0 to specify no limit. Set this value to the desired concurrency. For more information, see File Transport Configuration Page in the Oracle Fusion Middleware Administrators Guide for Oracle Service Bus.
