<lightning-record-form> performance regression introduced in Spring 20
Last updated 2021-10-12 ·Reference W-7216040 ·Reported By 6 users
Summary
LWC component which has the compound address field from Accounts object, loads fine in winter 20 org (~400MS ) but in the spring 20 org takes time to load (~30 seconds).
If we use the same component in some other page, then that page freezes and the address fields do not load successfully.
Repro
.html:
======
<template>
<div class="slds-grid">
<lightning-record-form
object-api-name={objectApiName}
fields={fields}
columns="2"
density="comfy"
onload={formLoaded}
onsuccess={formSuccess}
mode="new"
></lightning-record-form>
</div>
</template>;
.js:
====
import { LightningElement, api, track, wire } from "lwc";
import { getObjectInfo } from "lightning/uiObjectInfoApi";
import { createRecord } from "lightning/uiRecordApi";
import { updateRecord } from "lightning/uiRecordApi";
import ENGAGE_ID from "@salesforce/schema/Engagement__c.Id";
import ENGAGE_NAME from "@salesforce/schema/Engagement__c.Name";
import ENGAGE_ACCOUNTING_STATUS from "@salesforce/schema/Engagement__c.Accounting_Status__c";
import ENGAGE_AFFILIATED from "@salesforce/schema/Engagement__c.Affiliated__c";
import ENGAGE_ACTIVE from "@salesforce/schema/Engagement__c.Active__c";
import COMP_ADDRESS from "@salesforce/schema/Account.BillingAddress";
import USERID from "@salesforce/user/Id";
export default class HlEngageSumAppBusinessAddressTest extends LightningElement {
@api objectApiName = "Account";
fields = [COMP_ADDRESS];
}
Observations:
=============
In Winter 20 org →
>>Go to one account record and click on "test22" button
Notice it takes 4 seconds to load.
In Spring 20 org →
>> Go to the account record and click on "test22" button
It is taking 36 seconds to load.
Workaround
Do not use compound field.
