Java vs. C/C++ Performance Panel

Tuesday, 1:35pm - 2:25pm

Abstract:

This is a question that almost everyone doing a major project asks: should I use C++, or Java, or C#? Maybe it is more abstract than that, such as, should I use native code, like C++, or a managed runtime, like Java? Mostly, this is a matter of taste. Or is it? When it comes to ultimate performance, most applications are native, C++/C, with even having some hand crafted assembler mixed in.

But can Java, or any managed runtime in general, do nearly as good? Or maybe it could do better than native code. What could applications do to leverage the most out of these languages? With C++11, has the game changed? With Java 7 or 8, has the game changed? Or has the game really changed with the acceptance of Erlang? These and more, fellow developers, will be questions asked on this panel. It is native code vs. managed runtime in the game of performance!
