SPLK-1002 Advanced Searching and Statistics Practice Question
A search using `tstats` to query a data model returns results but is slow. Which of the following is the most likely cause?
⚠ Common exam trap
Splunk often tests the misconception that `tstats` always uses acceleration or that a `where` clause on a non-indexed field is the primary cause of slowness, when in fact the absence of acceleration is the most common and impactful reason for poor `tstats` performance.

Correct answer & explanation
✓
The data model is not accelerated.
When a data model is accelerated, Splink pre-computes and stores summaries of the data in a TSIDX index, allowing `tstats` to query these summaries very quickly. If the data model is not accelerated, `tstats` must scan the raw data in the index, which is significantly slower. Therefore, the most likely cause of slow `tstats` performance is that the data model lacks acceleration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The data model contains too many fields.
Why it's wrong here
Number of fields does not directly cause slowness; acceleration handles it.
- ✓
The data model is not accelerated.
Why this is correct
Without acceleration, tstats runs against the raw data and can be slow.
- ✗
The search includes a `where` clause on a non-indexed field.
Why it's wrong here
tstats can only use fields defined in the data model; but slowness is typically due to lack of acceleration.
- ✗
The search uses `from` instead of `index`.
Why it's wrong here
Using `from` is standard for tstats; it does not cause slowness.
