Usually C/C++ outperform in almost all kinds of processing. All scientific operations and calculations needs high performance. For illustration purpose I tested simple program which prints from 1 to 10 million using C, C++ and JAVA. C++ program takes on an average of 33 sec, JAVA takes on average of...

Usually C/C++ outperform in almost all kinds of processing. All scientific operations and calculations needs high performance. For illustration purpose I tested simple program which prints from 1 to 10 million using C, C++ and JAVA. C++ program takes on an average of 33 sec, JAVA takes on average of 84 sec and C took 26 sec to print on a dual core 2.6 ghz mac. From Benchmark game these are the results for JAVA and C++ (C++ beats in all cases if speed is taken consideration). Java vs C++ g++ (64-bit Ubuntu quad core) But again, you will enjoy the performance of C++ only when it is well written and optimized. If not, you don’t see any difference between it and java. Java is also a beautiful language and it is meant for developing enterprise web applications and it has an inbuilt powerful garbage collection mechanism which C++ lacks and programmers have to take responsibility of destroying the unused objects. read less

JIT vs. Static Compiler As already said in the previous posts, JIT can compile IL/bytecode into native code at runtime. The cost of that was mentionned, but not to its conclusion: JIT has one massive problem is that it can't compile everything: JIT compiling takes time, so the JIT will compile only some parts of the code, whereas a static compiler will produce a full native binary: For some kind of programs, the static compiler will simply easily outperform the JIT. Of course, C# (or Java, or VB) is usually faster to produce viable and robust solution than is C++ (if only because C++ has complex semantics, and C++ standard library, while interesting and powerful, is quite poor when compared with the full scope of the standard library from .NET or Java), so usually, the difference between C++ and .NET or Java JIT won't be visible to most users, and for those binaries that are critical, well, you can still call C++ processing from C# or Java (even if this kind of native calls can be quite costly in themselves)... C++ metaprograming Note that usually, you are comparing C++ runtime code with its equivalent in C# or Java. But C++ has one feature that can outperform Java/C# out of the box, that is template metaprograming: The code processing will be done at compilation time (thus, increasing vastly compilation time), resulting into zero (or almost zero) runtime. read less
