Question

State some reasons for the low performance of Tableau? Explain in detail.

Answer 1

Following are the reason for low performance

• Filters - filters need to create an extra query and if it used in large numbers and inefficiently then they can reduce the performance. So, it is advised to use filters whenever it is mandatory
• Live connection - Tableau extract works much better in comparison with a live connection.
• Data sources - a wrong query to a wrong data source can reduce performance. Also, the data source’s performance can also affect Tableau’s performance.
