Just giving some more input. We moved from having one 4 cpu master and one 8 cpu slave. Read were distributed between them. The new setup has a 2 core master dedicated to just writes and 3 8 cpu slaves with 16GB ram each dedicated for reading. The 16 new CPUs are also quite a bit faster. So effectively we have slightly more than tripled the available database power. We recently did was to start using a CDN (content distribution network) named Panther-Express. So all /common/ files get cached out there and gets sent back from the closest host. All other files are cached, but their servers do an if-modified-since at least once a second against our backend. Another user visible change is that on Friday we are moving image serving of the wikia.com domain name. Images are going to be served from images.wikia.nocookie.net , there is no need to send any cookie data for the images, so to reduce bandwidth we are serving it from another top level. I hope no more of the upcoming changes are going to result in any scheduled downtime for at least a month or so.
