    Hi, and happy new year.
    I'm trying to find an answer for a question I've gotten from a colleague: How many blogs and users can a single wordpress network installation support?

    Secondarily: what are the database requirements for larger networks of wordpress blogs in a single network installation?

    Feel free to address one or both of these questions.

  2. How many blogs and users can a single wordpress network installation support?

    WordPress.com uses the same codebase and hanldes 28 million.

    what are the database requirements for larger networks of wordpress blogs in a single network installation?

    How large? One db can handle hundreds or even thousands. Then you can start sharding the db and scaling the b servers. Look at the Shardb plugin and HyperDB (from the people behind wp.com).

    There's no limit in the codebase. You only need to scale the servers - like you would with anything large.

    Excellent, thank you Andrea.
    We're realistically talking about a few hundred blogs within six months, maybe a few thousand within a year or two. Somewhere in that range. We've already taken Shardb into concideration.

    BTW; if I may direct your attention to this issue:

    Trying to find out if this is a real problem, and how to resolve it. The posts in the blogs in the installation seems to come up fine though.

    That's nothing one dedicated box can;t handle. Maybe two, with the second for MySQL.

    I had a site with ~600 blogs on a 768 megs of RAM vps for a while. Mind you, only a certain percentage of those sites were active at any time (which is normal).
