High-safety vs High-performance regarding instant reflection

I was reading for the SQL 2008 administrator certification and there is a question wither synhronous(high-safety) or asynchnronous(high-performance) mirroring reflects changes to the mirror server instantly. I would think that asynchronous transfer would be the fastest, but the stated correct answer to the question says otherwise.

It really winds up being a preference for the office you are working in.

Probably a good rule of thumb is that would grow, this can change.

Couple of great sites of performance issues:

Does asynchronous or synchronous mode synchronize faster to the mirror server?

Asynchronous vs synchronous mirroring has nothing to do with mirroring effectiveness or speed.  Asynchronous mirroring simply decorellates the mirroring operation from the source operation updating the records on the principal.  Speed of mirroring, any mirroring depends primarily on network throughput and mirror transactional throughput.
