The short answer is that it is designed around Ahmdahl's law (effective parallelization of work) as opposed to Moore's law (waiting for hardware with a faster clock rate). Almost every CPU powering desktops, laptops, and servers is now at least dual core, and the trend is rapidly expanding. The days of the frequency race are essentially over. So, now software must adapt to tap into the power of the hardware of today and tomorrow.
You may have heard that AS7 Final has been released! . I plan to say a lot about this, but before I do, I wanted to call attention to the many heroes whose contributions made this monumental release possible.
I am happy to announce that last week we officially kicked off the beta stream for AS7. This will be a very rapid biweekly release schedule up until we hit CR. So expect to see a lot coming from us very quickly.
Congratulations to the whole AS team on the release of version 6! JBoss AS 6 is a Java EE 6 compliant application server, so it includes built-in support for many of the technologies we talk about here: CDI, JPA 2, Bean Validation, EJB 3.1, JSF 2.0, Servlets 3.0, along with many major enhancements in other areas.
