Why SuiteCommerce sites are slow
SuiteCommerce uses server-side rendering with database calls back to NetSuite — that combination produces slow Time to First Byte if not tuned. Common culprits: unoptimized images (huge originals served to mobile), JavaScript bundles loaded synchronously, lack of caching for product data, and uncompressed responses.
Fix these and most SuiteCommerce sites cut their load times dramatically without changing a single feature.
