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.

Hard3In a multi-site indexer cluster, which setting controls the number of copies of data kept per site?
Hard4Which TWO performance-related tasks should be performed on a regular basis?
Hard5Which TWO tools in the Splunk UI assist in performance troubleshooting?
Easy6When a search is running, what does the 'Dispatch' directory store?
Medium7How can you verify the current health and performance of your indexers using the Monitoring Console?
Easy8Which command helps you understand if your search is retrieving too much data from the disk by analyzing the 'index_time' and 'search_time'?
Medium9A user complains that a search is slow despite having a small time range. The Search Inspector reveals 'event_count' is high, but 'scanned_count' is also high. What is the likely cause?

Easy17Which dashboard in the Monitoring Console provides the best overview of resource consumption per search head?
Easy18If a search head is overloaded with concurrent searches, what is the best strategy to offload the processing?
Hard19You are analyzing search performance using the Search Activity dashboard. You observe that 'Result Count' is extremely high for a specific saved search. Which optimization technique is most effective to reduce the load on the indexer?
Medium20What is the impact of having too many small buckets in an index?
Medium21Which THREE factors commonly cause high CPU utilization on indexers?
Hard22To optimize search performance, which feature should be enabled to allow Splunk to pre-calculate results for specific reports?

Easy27Which configuration file is used to specify the disk path where index buckets are stored?
Easy28Which tool is best for monitoring the health and performance of the entire Splunk environment?
