301 Redirect - How Long Until Recovery?

[NealCabage]

How long after one moves a page and sets up the 301s should the site take to regain its previous rankings?

Context:  i've ported a site to a new framework. Along the way, several high ranked pages needed to have new URLs setup, as well as the site moved from www.domain.com to simply domain.com.  About 1 week after the change, the site's traffic went down 70% and has been there for about another 2 weeks.

I suppose it could be something about the new framework that is causing problems though according to SEOMoz tools, the new framework is checking out pretty well.  I assume the problem is reconciling all those old www inbound links with the new non-www location.  It is all 301'd however ... so it should be working, but is not.

So my questions are:

1. How long should it take Google to reconcile these changes and put us back to original SERP positions

2. is there something inherently problematic with switching from www to non-www?

Well ... no one responded to my question here, but it seems the problem has already corrected itself.  Perhaps it just took 2-3 weeks for link juice to be properly attributed to the new location of the 301'd site and subpages.  I'm not back 100% in terms of traffic yet, but I'm 80% there.
