Splunk Enterprise Certified Admin Practice Test

Is it recommended for Admins to turn off Transparent Huge Pages on Splunk Enterprise Servers?

1. Yes

2. No

3. Only in development environments

4. Only on Windows servers

The correct answer is: Yes

Turning off Transparent Huge Pages (THP) on Splunk Enterprise servers is indeed recommended primarily because THP can introduce latency and performance issues, especially in high-throughput environments common with Splunk. THP aims to improve memory management by using larger memory pages, but this can lead to increased page faults and, consequently, delays in memory allocation. Such delays could negatively impact the performance of data ingestion and searching in Splunk, which relies heavily on fast input and query capabilities. For systems that manage large volumes of data, like Splunk, it is crucial to minimize any factors that could slow down processing. Consequently, disabling THP helps ensure that memory management is handled more predictively and efficiently, optimizing overall system performance. Other options might suggest scenarios under which THP could be left enabled, but the most prudent approach in a production environment is to disable it altogether to avoid unpredictable performance issues.
