QuestionQ148

Performance Monitoring and Tuning

How does the average runtime across all searches relate to the number of CPU cores available on the indexers?

  • A Average run time is independent of the number of CPU cores on the indexers.
  • B Average run time decreases as the number of CPU cores on the indexers decreases.
  • C Average run time increases as the number of CPU cores on the indexers decreases.
  • D Average run time increases as the number of CPU cores on the indexers increases.
Explanation

Fewer CPU cores on indexers provide less processing capacity for search workloads, particularly concurrent searches, so searches take longer on average. Splunk recommends increasing indexer CPU cores for high concurrent search workloads.
