Measuring network latency
To measure and validate network latency between your Amazon EC2 instances and Oracle Database@AWS databases, we recommend using sockperf, an open-source TCP-level latency measurement tool. sockperf provides complementary network metrics that help you:
Establish network performance baselines
Compare performance before and after infrastructure changes
Validate that sub-millisecond latency targets are being met
You can also use Oracle database performance tools such as Automatic Workload Repository (AWR)
