Is Managed Code Slower Than Unmanaged Code?(grimes.demon.co.uk)

submitted by terrble(1665) 3 years, 10 months ago

Ask anyone the question above and they will say that managed is slower than unmanaged code. Are they right? No they are not. The problem is that when most people think of .NET they think of other frameworks with a runtime, like Java or Visual Basic; or they may even think about interpreters. They do not think about applications, or what they do; they do not think about limiting factors like network or disk access; in short, they do not think.

I would down mod if I could because the premise isn't "are managed applications slow" but "is the code slower". I read "code" as the codes, or IL v. native machine language. Applications, what they do, network or disk do not come into play with speed test of "codes" it comes into play with speed tests of applications.

JIT'ing the managed code before comparing execution speeds seems to defeat the point of comparing them at all.

Interesting article but please do something about the background.

I would like to see some partial trust results as well.

Wow, that background is really bad. Thought I had a bunch of broken pixels on my LCD... Adblock "http://www.grimes.demon.co.uk/images/bkgnd.gif"

The problem with this test is that FFTs can benefit tremendously from SIMD optimizations, which you can't do in managed code. In real life, a properly optimized C++ FFT algorithm on any modern x86 cpu would beat the pants off of a managed app, and will continue to do so until the JIT engine can vectorize.
