With such a large amount of content, searchability was essential. For this we built a custom technology stack based on Solr, Lucene and Haystack. Then, to keep all the previous links pointing in the right direction, we created a customizable scheme of Django regular expressions and Apache mod_rewrites.
A command line tool for grabbing real time stats from memcached.
A couple of good things to remember here: #1 resolving 1 bottleneck can open another bottleneck that is much worse. #2 is to understand that not all API’s are created equal. Additionally the configuration and setup that works well on one system may not work well on another. Because of this people often leave lots of performance on the table. Don’t just trust that your current API or config is optimal, test and make sure it fits your application.
