This article discusses a small-scale benchmark test run on nine modern computer languages or variants: Java 1.3.1, Java 1.4.2, C compiled with gcc 3.3.1, Python 2.3.2, Python compiled with Psyco 1.1.1, and the four languages supported by Microsoft's Visual Studio .NET 2003 development environment: Visual Basic, Visual C#, Visual C++, and Visual J#. The benchmark tests arithmetic and trigonometric functions using a variety of data types, and also tests simple file I/O. All tests took place on a Pentium 4-based computer running Windows XP. Update: Delphi version of the benchmark here.

I believe that -fomit-frame-pointer is not enabled at any optimization, therefore it's curious that it's specifically enabled for Visual C++, but not for gnu. Also, there's the potential that better performance would result from -O2, and then selectively optimizing from there, rather than going all the way to -O3.
