Hi napo chen,
First off the parallel query feature ONLY works on Server and not Desktop, and secondly it doesn't work against the same data source as the parallel feature only works across DIFFERENT data sources. One work around which may not be practical but certainly one to consider is to duplicate your data sources.
Here is a knowledge base article if you want to know how all of this works

To double confirm. I put 5 worksheets in 1 dashboard. Each worksheet has 1 SQL against the same data source. Tableau server will execute those 5 SQL in Sync or Parallel?
That would be processed in parallel, don't forget that you will need to duplicate your data sources five times then as it only works across different data sources.
