Question 38/138

There are user complaints about slow render times of a custom data table within a visualforce page that loads thousands of Account records at once.
What can a developer do to help alleviate such issues?

A. Upload a third-party data table library as a static resource.

B. Use the transient keyword in the Apex code when querying the Account records.

C. Use the standard Account List controller and implement pagination.

D. Use JavaScript remoting to query the accounts.

Correct Answer: B

On further analysis, C makes more sense. The page is loading thousands of records, that's the key wording

Answer is B

Itay Eshet - Oct 11, 2022

I think C is more correct because apex:dataTable has a limit of a thousand items so to load thousands of Account records the page must be readOnly (for limit 10000) and I tried and the internal view state is bigger than the account list so the difference of serialization time is probably smaller than the time it takes the browser to add all the html. And using transient means doing the query again on each page update (which takes more time), and if that's OK, why use a property at all?
