Question #: 99
Topic #: 5
[All Platform Developer II Questions]

Refer to the Aura component below:

A developer receives complaints that the component loads slowly.

Which change can the developer implement to make the component perform faster?

Show Suggested Answer Hide Answer
Suggested Answer: D

The correct way to fix this is to add Test.startTest() before and add Test.stopTest() after Line 18 of the code. This will reset the governor limits for the code that executes between these two methods, and allow the test to run without hitting the SOQL query limit.The Test.startTest() and Test.stopTest() methods are used to test code that makes a lot of queries or calls asynchronous methods12. By using these methods, the developer can isolate the code that needs more resources and verify that it does not exceed the governor limits.

I've got a better idea - let's just turn the whole component off. That'll make it load lightning fast, am I right?

User 1: That's one way to solve the problem, but maybe we can try optimizing the component instead.

Changing the default for showContactInfo to 'False'? Really? That's like putting a bandaid on a bullet wound. Not sure that's gonna help much.

Changing the type of contactInfo to 'Map' might work, but won't that just add more complexity? C'mon, let's keep it simple.

Hmm, moving the contents of c:contactInfo into the component seems like a no-brainer to me. Less network requests, faster load time. Easy win!
