This is a video about scaling the blogging site wordpress.com using techniques like WP-Cache and horizontal database partitioning using a "a plugin" called HyperDB.
The video is really interessing, but I woundered about the calculation of the maximal number of pages views possible with several configurations. The speaker claimed for example that the base wordpress installation can handle 8 requests per second and the can therefore handle 691.000 requests a day. But this is only true if the requests are uniformly distributed around the day.
When I plan to handle the requests even at the peak times (I mean day peak times not really extraordinary events like a Digg-attack), you can handle 8 requests per second at the peak, not on the average. Using the average over-the-day distribution of juli-blogs.de (based on the hours average) with peaks at 19h, I get a number that is smaller by more than a factor of 4. And even that is highly aggregated and not conservative calculation. Ok, even that number is clearly high enough for most wordpress sites (sure for dirkmeister.de ;-) )
