Independent streamfwd (HEC) tests - TCP/UDP raw events

This page provides performance test results for an independent streamfwd binary sending data to indexers using HTTP Event Collector (HEC) and TCP/UDP 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.
