Flow takes 10 minutes to create 175 SharePoint Items

[Power_Robert]

Hi,

I have a manually triggered flow that parses a json file and creates SharePoint List items.  The json file is pretty basic, but there a few thousand records in the file. It all seems very slow; it takes 10 minutes to process about 175 records into SharePoint List items. How is this possible?

I have 8 files to process and it is running over an hour now and it has only created 1700 records. How can this be so slow?

The compose has a trim function like this. But also without the compose steps and using the data directly into the Create Item it is taking forever: 

if(empty(items('Apply_to_each')?['telnr_prv']),'',trim(items('Apply_to_each')?['telnr_prv']))

Is there anything I can do to improve the flow to make it run faster?

Hi!
Power Automate is not the best tool in terms of performance, but you can probably improve it.
For example, does you requirements allow 'Apply to each' to iterate in paralel instead of sequentially, which is the default?
If so, go to 'Apply to each' settings, and activate it. You can play with the level of paralelism (max 50 items)

It's difficult to say which is the step that impacts performance the most... you can figure out by checking flow execution
Hope this helps

Just an update:

I had to change the flow a bit to make sure no duplicate records are created. It has now been running for 36 hours to create about 37.000 records; I have 8 json files with max 5000 records each. I started a flow for file 1, changed the file name and started the flow again until there were 8 flows running simultaneously. So each of them has so create max 5000 records.

So it takes more then 36 hours to create max 5000 records? And is still has to create about 11000 records.
