Slow execution

Questions
1

I have a SET node which caclulates a new value from other two in the previous node. It is a basic math calculation, but it takes really long to execute.

I have 10 items that the function need to go throug and it takes 126145 ms to execute. All the other nodes before that execute really fast.

This is the expression:
{{Math.round($node[“Merge5”].json[“count_stayover”]/$node[“Merge5”].json[“rooms_for_occupancy”]*100)}}

Any idea why this takes so long? Is the expression not ok?

Welcome to the community @aljaz86!

Can not think of a reason why that should take that long. Can you maybe share a simple version of the workflow you experience that behavior you can share that we can have a look?

Does this help in any way?

The example (input) values that get calculated are:
34/108

And when I am building the expression already my browser freezes for a while.
