[Mono-dev] Mono runtime performance

[Graeme Geldenhuys]

Hi,

I came across a article on the net, that compares different languages and 
there performance (Java, C#, C++, etc..).  I thought I would try something 
simular, but testing the execution speed of the .net runtimes for Microsoft 
.NET 1.1 and Mono 1.1.8.3

I compiled the C# benchmark application using Mono. It didn't make a 
difference which framework I used to compile the benchmark application, as the 
result was very simular.  I also didn't include optimization params to the 
compiler, otherwise Microsoft's .NET can't execute the Mono created 
application. (I got no idea why, but it does work other way round).

Anyway, the result was shocking!  The mono runtime was about 67% slower than 
the microsoft runtime.  Anybody know why?  I was testing this under Windows 
2000 Pro + SP2 applied.  My PC is a Dell Inspiron 9100 laptop with a 3000Mhz 
P4 and 512mb RAM.

Below is the output of the same executable, first run under Mono, then under 
MS's .NET framework.



Test System:
 Dell Inspiron 9100 laptop
 Intel P4 3000Mhz
 512Mb RAM
 OS: Windows 2000 Pro with SP2

Microsoft.NET Framework v1.1.4322
Mono .NET Framework v1.1.8.3

Compiled with Mono 1.1.8.3 and no optimization
(even with optimized compiler settings, the results are very similar)

I didn't write the Benchmark.cs application, I got it off the net.  I will 
include the code in the next email if anybody wanted to test it themselves.
