Using MySQL asynchronous calls to increase performance and user experience
summary
MySQL 5.6 still limits one query, one CPU core, so splitting heavy queries into parallel pieces using bash threads or PHP asynchronous calls runs many queries at once and behaves like MapReduce across CPUs or slaves. A complex 100 GB report that ran 15 minutes drops to about 8 minutes by running 24 background threads, and JavaScript/Ajax fetches counts asynchronously to show results immediately while async inserts defer logging so page load stays fast.
