Performance Tuning

This domain covers tuning Splunk Enterprise search and indexing performance: distributing search load, sizing and placing index buckets, using Search Activity dashboards to find expensive searches, and enabling acceleration features. Questions are scenario-based, asking you to pick the best optimization or configuration change for a described bottleneck.

What this domain covers

What to know about Performance Tuning

Be able to diagnose search and indexing bottlenecks and apply the right fix: distribute searches across peers, set bucket paths in indexes.conf, and enable acceleration for repetitive reports. The key is matching the observed symptom to the correct Splunk configuration or feature.

Offloading search load via search head clustering and distributed search peers

Setting index bucket storage paths with indexes.conf and related index settings

Using the Search Activity dashboard and Monitoring Console to find costly searches

Enabling report acceleration and data model acceleration to precompute results

Watch out for

Common Performance Tuning exam traps

  • ▸Confusing indexes.conf with server.conf or inputs.conf when asked where bucket paths are defined.
  • ▸Assuming adding search heads alone fixes load without distributing searches to indexers or peers.
  • ▸Trying to optimize a heavy search by only changing time ranges instead of reducing result count or using acceleration.
