>>RV consume so much resource and are so slow. They're great tools for analysis (tuning the project), but s l o o o w for a production system.
The only stats I've ever seen show RVs performing at about the same level as SPT and SP, slightly slower in some cases, slightly quicker in others. Check it out on the Wiki.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
