So we don't really care about the parser's "top speed".
We are talking about different things. I don't consider callbacks made when processing "magic words" or "parser functions" being part of the actual parsing. The reference case of no markup input is interesting to me as it marks the maximum throughput of the MediaWiki parser, and is what you would compare alternative implementations to. But, obviously, if the Barack Obama article takes 22 seconds to render, there are more severe problems than parser performance at the moment.
