Workflow optimization

Question

Hi All
I am very new to Alteryx. I am trying to optimize my workflow, taking two hours to process. My current workflow has two workflows, and I am doing union at the end. Individually both workflow works very fast and takes around 15 to 30 min individually. But when I union them, the process gets slow. I have checked the schema, and both flows have an identical schema.

Only Union tool might not taken that much long time.

The case may be, some earlier tolls taking longer time, like data cleansing

Need to check earlier tools

Without looking at the flow, can not really say anything.
But Uniton just simple vertically combines the data, it is strange that it will take that long time.

Can you try to output the two data stream to yxdb, then use a new flow to read them in  and combine and see there is any improvement?
