How to Boost the Performance of a Tableau Dashboard?
Tableau is a significant platform for data visualization enabling users to create and share insights. However, with Tableau’s features being released consistently, BI services are blooming more than ever. But with great features come efficiency issues in managing your dashboards to keep their performance above par. Simply put, you need to learn and master the performance-boosting methods for your Tableau dashboard.
Any business that uses Tableau for business intelligence services would agree that performance matters. This article is for you if your business deals with huge chunks of data and you are stuck with a slow-loading dashboard. This blog discusses Tableau’s dashboard performance in a bigger picture covering all its crucial components.
Tips to Design
an Efficient Tableau Dashboard
● Keep your data clean to match it better with your questions’ structure. This makes your dashboard faster and optimizes your work speed.
● Dashboards could be made even faster with extracts. They are an easy and quick way of boosting workbook speeds. So, if your business doesn’t deal with real-time data or processes vast chunks of data rows, then you should try it.
● Most of the slow dashboards have a poor design that ruins the whole user experience. Specifically, keeping too many charts over a single dashboard or representing a lot of data at once. Instead, you should keep it simple and enable the users to drill down to details incrementally rather than getting everything on the dashboard.
● Keeping irrelevant data adversely affects your Tableau software’s performance - both in terms of the fields you refer to and the granularity of the records you return. Thus, using filters, aggregating, and hiding unused fields is an intelligent choice.
● Remember that strings and dates are slow, while booleans and numbers are fast. So, try incorporating the faster ones in BI processes.
● Always keep your Tableau software updated to its latest version, as it consistently brings enhancements to improve user experience. So, this might automatically boost your dashboard performance to some extent.
● If none of the updates resolves your problem, you should start looking for the components that act as major performance blockers. It might be long-running queries, slow calculations, multiple queries, or complex rendering. Getting insights from these areas will help you focus in the right way.
● In some instances, if Tableau works slowly in the data source, it would be slow for Tableau Desktop. But if it is slow in Tableau Desktop, it would always work slowly in the Tableau Server. This clearly describes that Tableau’s dashboard performance is highly dependent on the context of your environment. Any functionality running well in one case might not perform well in another. Thus, test and iterate your BI software to determine what works best in your specific case.
