Rest API call improve performance in OIC

Summary:

Improve Performance while doing rest call in OIC

Content (required):

We have a requirement where we need to call an Oracle Project Rest API which updates the task DFF attributes and each API call takes around 1 min to process. We are using loop and have around 2k projects to update but calling the REST API it's taking around 2000 mins. To improve this, we used to parallel and loop and it optimized performance, but is there any better way to do the same with reduce time.
