This was done by c't, not mysql. But the article title is misleading: it
doesn't compare database systems, but application tuning. Unfortunately,
the prerequisites where quite mysql-drawn right from the start. The
MySQL team did a very good job tuning the existent application to access
the database as rare as possible using memcache, and dropped all
constraints (no surprise...). Porting _that_ optimized app to pgsql
would be really interesting and comparable.
