Impact Area

Performance

Severity

Low

           Affected Element

Apex Page

## Rule ID

**SF-0123**

## Impact

Pages which do not include custom components are likely to be using an eager (not lazy) data fetch strategy.

## Remediation

To reduce or delay expensive calculations or data loading, use lazy loading, a technique in which a page loads its essential features first and delays the rest.

### Time to fix

30 min
