Independent streamfwd (HEC) tests - default configuration

This page shows performance test results for an independent streamfwd binary sending data to indexers using HTTP Event Collector (HEC) and default stream configuration . For detailed test environment and configuration information, see Splunk Stream test environments in this manual.

Note: splunkd CPU % and Memory MB performance metrics do not apply to streamfwd when sending data to indexers using HEC.
