JSM Form load time is slow

Summary

Summary of Issue

When a customer tries to fill out a Form configured for the Customer Portal, Form Field drop downs are taking upwards of 5 seconds to populate the values related to the dropdown Form field.

Environment

The customer is using Forms for some of their Request Types, which include both Form fields linked to Jira Custom Fields and Form Fields with Data Connections.

Diagnosis

This is ultimately expected behavior for Forms as we don't have control over Data Connection Performance since it is an external call from a different application into the JSM Data Connections.

Cause

This issue is caused because the performance of any Form field (whether connected to a Data Connection or not) will be affected by this when the Form loads. For example, if you were to gather a HAR log or view Developer Tools for the web responses of the Form/Webpage you would see a call to `/api/3/portal/2/requesttype/11111/formchoices` which takes many seconds to load. This single endpoint is used to fetch all the data for the Data Connection(s) + options for linked Jira fields. So in this scenario, we will need to wait for the Data Connections to fully load into the page before any dropdown Form field options are available.

Solution

The only way to resolve this performance issue with Forms is to remove the Data Connections from the Form.
