How to achieve great performance to calculate Total column in the get item sharepoint list

[Heli2911]

I want to calculate certain column based on group of data from sharepoint list, then the result would be array that collecting a group of data with total column. Moreover I've created the flow to achieve this with variety of time on the executions start from 2mins until 7mins (with same data) which are low performance for me.

Below are my flow :

1. Select 2 -> this is for throwing away unnecessary column

2. Apply to each 2 -> based on 'UniqueName' that contain data we want to group

3. Filter by Series -> to group the data based on 'UniqueName'

4. Calculate Total Downtime -> to calculate the column based on 'Filter by Series'

Below are the time execution of the flow :

 Is there any way to sum of the certain column in the sharepoint list to be faster in the execution?

Hello @Heli2911

Can you enable concurrency on your loops.

This can be done by clicking the 3 dots on your apply to each loop.
Than click settings,
Now turn concurrency on,
And set it’s value to 50.

Do this for every apply to each loop.

hi @Jcook ,

Actually I did your recommendation on the "Apply to each 2", yet the time execution is need 2-7 minutes.
