Are you struggling with application performance issues?

Imagine having a tool that can automatically detect if you are using JPA and Hibernate properly. No more performance issues, no more having to spend countless hours trying to figure out why your application is barely crawling.

Imagine discovering early during the development cycle that you are using suboptimal mappings and entity relationships or that you are missing performance-related settings.

More, with Hypersistence Optimizer, you can detect all such issues during testing and make sure you don't deploy to production a change that will affect data access layer performance.

Hypersistence Optimizer is the tool you've been long waiting for!
