Sun’s VirtualBox virtualization software release offers interesting features that allow developers to measure multicore scalability. As these new features were not available in previous versions, it is very important to consider them when evaluating a virtualization solution in order to test parallel performance in different operating systems and hardware environments.
Talking about information systems, scalability is an application’s ability to upgrade its performance, its response time or the number of users to which it can provide services. We can measure scalability from many points of view (among others):
* Processing capacity.
* Features and services (new functions, new cards, new hardware).
* Storage capacity.
* Memory.
One of the great difficulties related to multicore programming is the possibility of testing the application’s scalability using different hardware and diverse operating systems. If you develop an application without multiplatform in mind, you may still have to test it on different operating systems.
