System Env:

• Server: Dual XeonE5-2670 v2 2.5GHz; 64GB DDR3; 512GB SSD
• System clock precision is +/- 1 ms
• 1Gbps NIC
• JAVA_OPTS="${JAVA_OPTS:--Xms8G -Xmx8G}"

ONOS Apps:

• drivers
• null

ONOS Config:

• cfg set org.onosproject.net.intent.impl.compiler.IntentConfigurableRegistrator useFlowObjectives true (when using flow objective intents compiler)
• cfg set org.onosproject.net.intent.impl.compiler.IntentConfigurableRegistrator defaultFlowObjectiveCompiler org.onosproject.net.intent.impl.compiler.LinkCollectionIntentObjectiveCompiler (when using flow objective intents compiler)
• cfg set org.onosproject.net.intent.impl.IntentManager skipReleaseResourcesOnWithdrawal true

Test Procedure:

• Intent batch installed from ONOS1
• Record returned response time

Note: Error bars in the graphs below represent standard deviations. Only the upper error bars are shown.

Following graphs include results using flow rule stores with both strong consistency and eventual consistency models. The ONOS team is still working on performance improvements for flow rule store with strong consistency.
