A duplicate resource is an image, script, or stylesheet URL referenced more than once in one measured HTML page. NOTABIS ignores the normal preload-plus-stylesheet pair and reports other repeats for review.

Large HTML can increase transfer and parsing work, but size alone does not prove a page is slow. NOTABIS flags responses over 500,000 bytes so you can inspect the content and delivery path.

A slow response finding means the measured request took more than two seconds in that audit. Investigate server work, database calls, caching, network path, and load before choosing a fix.

A render-blocking finding identifies markup patterns that may delay first rendering. It is a candidate list, not measured proof of user-visible impact; validate changes with performance evidence.

Cache-Control tells clients and intermediaries how a response may be stored. Missing policy is a configuration review, not proof that a page is slow or that one universal cache setting is safe.
