I always get flamed when I mention this (I don't mind it, btw) but...
I find it pretty interesting that for the DB write-intensive portion[0] of the TechEmpower web framework benchmarks, you must go further than entry 150 (sorted by most requests-per-second) to find MySQL used, compared to PostgreSQL or Mongo. For the DB read-intensive portion[1], only 15 of the top 100 use MySQL (the rest in that bracket use PostgreSQL), and the first entry there comes in at number 44. Important: if you examine the entries, you'll find that some of the frameworks have multiple listings for different configurations, including the use of MySQL vs PostgreSQL (in other words: same framework, but only the DB is different, in the same test).
