HyperDB definitely looks like a more robust solution, and I'd be much more comfortable using the official wordpress.com database scaling method. I wound up using multi-db for 2 reasons. 1. IT was getting cranky and I needed to make them happy ASAP. 2. I couldn't find any documentation about how to actually configure HyperDB, beyond the stub documentation on the project website. I'll explore a bit more, and will plan on migrating from multi-db to HyperDB as soon as I can - now that IT is happy, I have some more time to fully research and plan scaling the database. Fun with organically growing community resources :-) Andrea, thanks for the clarification.

So it'll be around. If it’s a huge concern (and it definitely gives pause) Hyper DB, despite its name, is also a multiple db configuration AND is Open Source, AND is exactly what wp.com uses.

I'm not even running WP-Super-Cache at the moment, but will turn it on if needed.

Were the backup problems the primary reason why you made the switch or was it performance? This is something we will have to consider over the summer. We are close to 300 blogs now but have not noticed a real change in cpu and memory usage and we have been averaging just over 100k/page views day the last few days. Might be the PHP APC and MySQL Qcache are saving us. Thanks for posting this, very helpful. Were the backup problems the primary reason why you made the switch or was it performance?

The license.txt file that ships with the code reserves full copyright to Incsub - which is fine, but means a fork is of questionable legality without Incsub first relicensing the code under a compatible license. Probably not a big deal, but definitely something to keep in mind. maybe, but the code isn’t GPL, or any other license that would allow others to pick up the gauntlet.

They based their work on the work of another, and given the script is crucial for a big WPMu setup---and there are many of them now---I think we're in good shape. I hope, I pray!
