NGen

[Markus Wöß]

Hi!

How can I test if the .NET runtime uses the native image produced by ngen???
I have played a little bit around with ngen, but I haven't noticed any speed
difference. Perhaps I have done something wrong - so I wonder how I can
approve that I have used ngen correctly...

Have fun

its stores the pre JITted (NGEN generated) assembly in the assembly cache

 

[Markus Wöß]

yes that's true,
but the fact that there is a JITed assembly in the cache doesn't mean that
it is really used (there are several cases like for example different
hardware, ....)

so how can I test at runtime if the preJITed image is used?

check the fusion log.

search MSDN for FusLogVw and have a look at

Hi Markus,

I suggest that you can use Process Explorer to check whether the
nativeimage of your assembly is loaded when executing. You can download the
link from the link below:

Hope this helps.
