That operation should be fast, as it should be hitting the cache from having just rendered it.
Calling $wgParser->preprocess() won't hit the parser cache, I don't think. I also don't think preprocessed wikitext is cached at all, just the HTML output.

Not the parser cache, but the preprocessor one, see includes/parser/Preprocessor_DOM.php:105 preprocessToObj() function. Text bigger than $wgPreprocessorCacheThreshold has its xml serialization stored in the objectcache for a day.
You are right, however in that it isn't the full preprocessed output.
