Yet anoyther object relational mapper
This object relational mapper makes heavy use of information_schema in mysql,
per default queries to this schema triggers recalculation of statistics every
time it is queried which slows things down a lot. Try turning
innodb_stats_on_metadata of to stop mysql doing this.
set global innodb_stats_on_metadata=0;
There are forks of this project solving this with a memcached instance caching the schema information instead.
