Independent streamfwd (HEC) tests - HTTP raw events

This page provides performance test results for the streamfwd binary sending data to indexers using HTTP Event Collector (HEC) and HTTP raw events 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.
