If we were to select the most important MySQL setting, if we were given a freshly installed MySQL or Percona Server for MySQL and could only tune a single MySQL variable, which one would it be? MySQL comes pre-configured to be conservative instead of making the most of the resources available in the server. Why is that?

Multicore processors have huge amounts of available DRAM bandwidth – maybe it does not even make sense for a single core to try to use that much? To understand what is happening here, we need to understand the way memory bandwidth interacts with memory latency and the concurrency (parallelism) of memory accesses. Stay tuned!
