Blogging Roller

On the Roller dev list, Allen Gilliland recent asked Roller site administrators to share some stats. He asked for:

how many blogs does it have?
what is your performance like?
what are your cache size settings?
how good is your caching efficiency on average?
any numbers on how much activity the site gets? hits/visits? load?
server info?  processors?  ram?  OS?  webserver?  database?
how is stability?  does the server require restarts often?

Here are a couple of interesting stats. As far as we know, the biggest Roller sites are jroller.com with around 9,000 blogs, blogs.sun.com with about 1,600 and IBM internal blogs with about 1,200 blogs and 12,000 registered users (they require registration for comments).
