The standard WordPress MU installation requires only one database - which is great for hobbyists or people just looking to host a few dozen or few hundred sites.

However, when you get to a few hundred sites, especially if they are particularly active sites, things can start to get a little cramped in there as your database now contains thousands of tables and quite likely a fair bit of data too.

Which is where this package comes in.

You can use it on a new site or an existing site - and you don't need to be a technical genius to work it out (it's also exceptionally well documented and supported in our forums).

It allows you to split your single database into 16, 256 or 4096 database - and if you are using cPanel, even incorporates a script that will do that for you.

After that it'll distribute your blogs around the databases evenly - giving you peace of mind, much better performance and the confidence to grow your site as much as you desire!

It's the same solution we use on Edublogs.org and is very similar to that used on WordPress.com.

And, of course, as with all of our code here on Premium, we release upgrades with each new version of WPMU that requires them!
