Functionality is great, but what about performance? Java started life as a toy platform and quickly became an enterprise tool. Early on, evolution in performance and scalability went hand in hand with functionality improvements. However, virtually all subsequent improvements to the Java platform were in features and scope, with basic performance remaining largely unchanged. The result is that modern Java apps are powerful and flexible, but their performance can be iffy. Application instances now have a hard time consuming even a small fraction of entry level modern servers without incurring unacceptable and detrimental effects. In this presentation, Azul CTO Gil Tene explains how the Zing Java runtime platform eliminates the evolution mismatch and allows enterprises to consistently and reliably power their applications, making full use of modern server capabilities.
