Hello,
If the queries are complex, this is understable. I had a performance
review of a Hibernate project (Java Object Relation Mapping) using
MySQL. ORM produces easily "complex" queries with joins and subqueries.
MySQL uses nested loops for subqueries which lead to performance issues
with growing database size.
They state in their documentation that for version 5.2 there are
improvements planned regarding this kind of query.
Best Regards
Sebastian
