One thing that bugs me is whether to use the ngen tool or
to compile the code to run under certain processors,
using the compiler options G5, G6, ect...? Say i
deployed an app to a user running a pentium 4 on his
computer. I know that the ngen tool is used for start
up, but which would cause the app to start up faster,
ngen or the compilar options? Thanks!!

Hi Ramon,
I don't think that Gx options have any effect on managed code (I assume you
are talking about managed code) since it is compiled always to MSIL.
Thus NGEN on target machine is the only way to speed up managed code.

Are you sure the Gx options have nothing to do with
managed code, because the default compilation option is
O2 (or O3 i can't rem). With that option set, it
combines many of the other options into one, which is the
default release build. You could either use this default
or custom make your own. Are you sure the Gx options have nothing to do with

I am pretty sure that there is no point optimizing MSIL for a processor (I
don't have much experience with C++ optimitzations though) as this is the
work for ngen or jit.
However, you might try different optimizing options and see if they make a
difference in msil.

The compiler options you are talking about is for VC++ native mode only,
managed code compilers have no such optimization flags as they produce MSIL
code that get's optimized by the JIT compiler.

Ok i understand. I thought the options affected managed
code too. Yeah I am a straight VC++ freak, sorry for not
mentioning that. I figured the options for VC++ were the
same with C# because of the managed extension tacked on
to VC++. I thought those were .NET features. Thanks a
lot for your help Miha and Willy!! Ramon This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I have a question regarding the use of ngen.exe and dedployment.
I want to make sure I understand this correctly.
If I create an app that has an .exe as well as a couple of .dll's.
I can create a setup package, create a batch file (specifying the ngen
commands) run the install, call the batch file from within the setup program
and run ngen.exe on the .exe and .dll files.
This will create a native image in the machines GAC.

I have two assemblies, A.dll and B.dll.
A.dll contains two methods. One method, UsesB, uses a type from B.dll
whereas the other, DoesNotUseB, does not.
To cache a native image of A.dll with both methods precompiled, I believe I
can do
ngen A.dll B.dll

I have observed that the ngen process appears in the list of processes

I would like to know if this process can be a cause of slowing down

I'm trying to use the ngen tool from framework 2.0, to accelerate the load runtime of my app.
I'll explain here what I'm doing.
First I copy&paste the ngen.exe to the Bin folder of my project (to not have to especify the path), where is the .exe of my app.
Then, in the CMD, i go to the same folder to execute the ngen, and I've tried differents ways to create the native image.
