Hey @70000075
There are many methods to improve the performance.
The easiest I know is to open the option of concurrency.
Click on three dots of apply to each. Then click on settings:

After that open the concurrency option.

And increase the degree of parallelism to max, that is, 50.

So, what it does is, normally the loop will go to the value at 0 index or the 1st value, then to the 2nd value, then 3rd and so on. But with concurrency it checks all the things at the same time. So, setting it to 50 will check 50 items at the same time.
Just a note:
Dont use concurrency with variables, only use compose action.
Sometimes increasing it to 50 might slow down the process. So, find the value that suits best to you. You can keep it low to 10 also, or make it to 20, 25 or 30. Just find the appropriate value for yourself.
