gutefrage.net is a Q&A platform built with user-generated content. The company’s primary customers include users asking and answering questions, users searching existing answers, and advertisers. The heavily used platform currently has approximately 18 million unique visitors, 80 million visits, and 140 million page views per month, according to agof.de rankings.
To serve these customers, the company relies on four Percona XtraDB Cluster instances with multiple solid state devices (SSDs) and CPUs to handle the database load. Approximately 95 percent of the database load is “read” load.
