then why c# is much slower than java in linux? The link has this result too. As i just said, it is os+language, not just one of these.

You aren't comparing like for like. That's the problem, and I can't see how you don't get that. Java running on Linux runs faster because there's less overhead on Linux. How can you not understand this? If you are that obsessed with speed, write it in C or Assembly.

then why c# in linux is also slower than java in linux? Less overhead in linux cannot be a reason for this case.

C# on Linux is not an official product. It has nothing to do with Microsoft - it's implemented through something called Mono. There is no .NET for Linux.

This is a C# forum, not .net

Something else you don't understand.

C# is a only windows language? You think so?
|
|
|
|
|
What are you talking about?
C# runs within the .NET framework on Windows and under the MONO framework in Linux. If you don't understand that basic fact then you will never understand what people are trying to explain to you.

Of course I know, then what's wrong to compare c# and java in linux? Mono has been around for years and it can let c# runs pretty fast in linux, and some people say nowadays mono let c# runs even faster than in linux than the .net in windows.

Because they are different in so many ways.

so you agree C# cannot be fast than java with linux in any kind of OS or situation, cool.

No I don't agree, of course it can be faster. You really need to learn a bit more about these platforms, and even perhaps computing in general. And please, do not try putting words in my mouth in the hope of winning a rather specious argument.

Your argument is my question is not a programming question. The fact is that one of the main reasons for people to choose a programming language is because of speed. We would not use C++ just because we like it, we choose C++ because it is fast, and this is a good discussion about why it is fast. For the same reason, it is good to discuss why should we choose java or C#, and why it is faster under some environment, like windows or linux. Is that Java is specific designed to be ran faster in linux so that it can make c# less competitive? This is a good discussion. All of these are very good discussion related to C# and I cannot see why this post should not be in this C# forum.

Well it isn't, as I and a number of other CP regulars have tried to explain. If you cannot see that for yourself there is little more that we can do.

That is very rarely the reason these days.
crunchor wrote: This is a good discussion.
Perhaps, but it is still not a programming question, so it does not belong in this forum.

if speed is not an issue, then why would anyone use C++? It takes much longer time to develop the same thing comparing to c# and Java.

You really seem to understand absolutely nothing about software development.

That must be you. You sound like you like to use c# but not c++ just because you like the character #.

Your talk shows you are priceless.

And what does C# use? What do you have to install to use your C# code on.
Oh, and I am much more familiar with the forums here than you are. I've been doing this for a very long time.

You are very funny because you assume too much.

Like what? That you can manage to get C# to run without .NET (or Mono). Go on, tell me how you can manage it without access to either of these frameworks at any stage.
Let's face it. Your argument is getting desperate so you are now trying to change what it's about. Sadly, you aren't funny.

it is funny that C# with .net or mono in windows/linux, all of these combination is still slower than Java under Java Virtual Machine in Linux, you sound like agree a lot from so many replies. I know you just want to tell me C# is just slower than Java in Linux no matter what do you deal with C#, interesting passion from you. You are such a java lover.

Simple; they're not the same language, do not load the same runtime, and the runtimes do not have the same settings.
What are you trying to achieve?

You are discussing c#, that's good.
