Within a netflow summary page, below. The charts in the page take a long time to load. This page which holds the last 7 days of both Ingress and Egress data, has been loading for over 5 hours. The data eventually loads but only after the 5 hours for a single page. Any suggestions or potential cause of this issue?
You are loading a lot of data! You'd be better looking at a smaller time frame and if you really need to know who downloaded what 7 days ago, maybe just open up a NTA page just for that 24 hour period.
Rollups will make the data load faster as will a faster server where the database is located.
