We have multiple search heads that are available for different functions. We have one running alerts, and another dedicated to dashboarding.
Some of alerts & dashboards are real time, and perform real-time backfill. Other dashboards, that look at nearly the same data, perform historical analysis.
I want to turn on report acceleration, as I think it will speed up the historical analysis, but I have a few questions:
Report acceleration is excellent for rendering massive or sparse data sets quickly. You will see near instant results from an accelerated search. Report acceleration performed on a search head cannot benefit another unless you're using search head clustering.
