Which action can significantly improve system performance according to Adobe Commerce best practices?

Question

Options

• AFrequently refreshing caches
• BUsing local file storage for session data
• CEnabling all default modules
• DDisabling unused modules (e.g., 'Magento_SampleData')

• A
  6% (1)
• B
  6% (1)
• C
  12% (2)
• D
  76% (13)

Explanation

Disabling unused modules like Magento_SampleData reduces the amount of code loaded, registered, and executed on every request, directly cutting overhead from event observers, plugins, and database queries that those modules would otherwise introduce. Option A is wrong because frequently refreshing caches destroys performance - caches exist precisely to avoid redundant computation, and clearing them forces expensive regeneration. Option B is incorrect because local file storage for sessions is generally slower and less scalable than database or Redis-backed session storage, particularly under load. Option C is the opposite of best practice - enabling all modules maximizes unnecessary overhead; you should only enable what your store actually needs.

Memory tip: Think "less is more" - Adobe Commerce performs best when it only loads what's necessary. If a module isn't used, it's pure dead weight on every page load.
