Improve Dashboard Performance
|Knowledge Article Number||000213233|
|Description||Note: Dashboard refresh times can vary based on available resources. Since salesforce is built on a multi-tenant structure, dashboard refreshes are processed in a queue. So refreshes tend to complete faster off peak hours, when more resources are available. Other factors like caching can also affect dashboard refresh times.
|Resolution||But dashboard performance depends mainly on the performance of its source reports. If a dashboard is refreshing slowly, each report needs to be examined to find the slow running report(s). See here for steps on improving report performance.
Less commonly, dashboard performance can be affected by a performance degradation. These are instance specific and can be checked at status.salesforce.com/status
Also uncommonly, dashboard components can include Visualforce pages that cause performance issues. These can be identified in the Dashboard Edit page and will say “Visualforce Page” as the chart type.
