Hmm. I'll check again later. In the meantime, what I did in the great-grandparent post was just this, on a fresh start:
1. turn on profiling in wiki-arc/wiki-arc.arc, by setting the variable whose name escapes me at the moment to t
2. Load wiki-arc/wiki-arc.arc and (thread (asv)) the server.
3. Load a single test page, with various formatting, including '''a bolded text's attempt to ''confuse the parser''''', [[link]]s, [[sample link|links with different text]]s etc. etc.
4. (profiler-report)
I'll check later on it, and possibly also post the sample wikitext.
