Q1

I want to provide piwik analytics for more than 3000 users, in which total daily pageview is about 4M. Is it possible to serve this traffic in single machine?

#Q2
Similar to Sourceforge, I want to let users implicitly sign on piwik dashboard; the user types login information only once. The legacy system(e.g. sourceforge project admin page) and piwik would be in a different domain, but have to share auth status. How do I set up SSO-like authentication?

Q1: I don’t think 4M will make it on a single server. I suggest you try first with 0.5M, then scale up and see how things are doing.

Q2: there is no SSO plugin to use as an example or simply reuse, there is the LDAP plugin: http://dev.piwik.org/trac/ticket/734[/url] and the HTTP_AUTH authentication plugin: [url=http://dev.piwik.org/trac/ticket/514]http://dev.piwik.org/trac/ticket/514 which can help. Building a login plugin is very easy.
