Podcast #75 - Blog – Stack Overflow

Tom notes that if you have a small site that can be served by one box, any stack will do. If you have a medium site that needs hundreds of requests per second, go with what your team knows best. But beyond that, once you get the hundreds of thousands of queries per second, everyone builds a custom solution.
Oui, mais c'est tellement plus drôle de jouer les prophètes sur la fin des bases relationelles !

scaling drupal - an open-source infrastructure for high-traffic drupal sites | johnandcailin
by holyver & 1 other
in this article, i outline a step-by-step process for incrementally scaling your deployment, from a simple single-node drupal install running all components of the system, all the way to a load balanced, multi node system with database level optimization and clustering.
since you almost certainly don't want to jump straight from your single node system to the mother of all redundant clustered systems in one step, i've broken this down into 5 incremental steps, each one building on the last. each step along the way is a perfectly viable deployment.

LASVM is an approximate SVM solver that uses online approximation. It reaches accuracies similar to that of a real SVM after performing a single sequential pass through the training examples. Further benefits can be achieved using selective sampling techniques to choose which example should be considered next.
As show in the graph, LASVM requires considerably less memory than a regular SVM solver. This becomes a considerable speed advantage for large training sets. In fact LASVM has been used to train a 10 class SVM classifier with 8 million examples on a single processor.
