AWS Performance Metrics

Benchmarking Setup

The two test beds used to collect benchmarking data are depicted below.

Test Setup

HA Instances are launched on dedicated host.
PKTART Tools are also launched on dedicated host and flavor used is c4.2xlarge.
SweActiveProfile used for Pass-through call is Standard pass-through and for transcoded its Standard transcoded.
Bench-marking numbers obtained can vary based on AWS network and also currently we are facing issue with AWS infrastructure where we are not able to pump the call load >2000 per leg on c4.2xlarge.
Benchmarking data was collected from a private network.
