SPLK-1002 Advanced Searching and Statistics Practice Question
A company uses a large Splunk environment with many users creating dashboards. They notice that some searches are slow and consume excessive resources. What is the best practice to optimize search performance?
⚠ Common exam trap
Splunk often tests the misconception that `tstats` is only for advanced users or that it requires a data model, but the trap here is that candidates confuse `tstats` with `stats` and think any aggregation command is equally efficient, ignoring the critical role of summary acceleration.

Correct answer & explanation
✓
Use the tstats command with summariesonly=t
The `tstats` command with `summariesonly=t` is the best practice because it queries accelerated data models or summary indices rather than raw event data, drastically reducing the amount of data scanned. This command leverages pre-computed statistics, which is the most efficient way to perform searches over large datasets, especially when users are building dashboards that run repeatedly.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use the tstats command with summariesonly=t
Why this is correct
Uses pre-summarized accelerated data, significantly faster.
- ✗
Use the search command with a large time range
Why it's wrong here
Increases data scanned, slowing search.
- ✗
Use the eval command to create new fields
Why it's wrong here
Eval does not optimize search retrieval.
- ✗
Use the stats command with by clause on high cardinality fields
Why it's wrong here
High cardinality by fields can be slow and resource-heavy.
