I have a bunch of scheduled reports that run 15 minutes past the hour (with the window set to 'Auto').
The dashboard normally loads instantly, but takes a very long time when it's 15 minutes past the hour. It appears that the old cached results are deleted before the new run finishes, forcing the client to wait for the fresh data.
Is this a bug in Splunk, and if so, who can I contact?
just to verify, try and run the search that's behind the report and check how long it takes to populate
if it takes 2 minutes for example, try and open the dashboard at minute 16 and check how fast it populates
