Rendering a PDF is not istantaneous, it can take some time with complex
documents.

Memory usage refers to the caching strategy, not to the rendering speed (which
you nor okular cannot change anyway).

If you don't want to see empty pages, you could try to disable the "background
generation" in the permormance settings.
