Bad performance with nested classes and large amount of data when using Hibernate
In my JEE application, I am using the Hibernate framework as the ORM mapper. Initially, the performance was very good. However, as more and more data is gathered during the lifetime of the application, the performance is getting worse and worse.
The data model is rather complicated, and the entities are nested. Are there configuration options, that could help to improve the performance?

Using joins (mySQL) in a query
Actually in a web application performance has a huge influence on usability. So I often use joins in my queries to provide compact sql queries. But queries with many joins have a bad performance and the user have to wait for a long time. Is there a better opportunity to provide a better performance?

Speeding up project using Zend_Db
<p>An existing project realized with the Zend Framework should be optimized in terms of performance. The use of Zend_Db slows down the database access because of its automatic table-scanning and overhead. The SQL-queries as well as the table structures are already optimized and should not be changed. The configuration on the server environment:</p><ul><li>PHP 5.2.6</li><li>MySQL Server Version: 5.0.75</li><li>Zend Framework 1.5</li><li>Apache 2.6.28-16</li><li>Suhosin-Patch 0.9.6.2</li></ul><p>The update to a newer version of Zend Framework is right now not possible because of some migration problems. The changes in the code should be measurable and viewable with XDEBUG/kcachegrind.</p>
