.Net 2005 works slowly than .Net 2003

Hello,

The same code works slowly for Visual C++ .Net in 2005 ( Release mode )

We have these compilation options for 2003

cl -nologo -c -FoWIN32/advfrnt.o -MD -O2 -G7 -W3 -GR -EHsc -DIFORTRAN -Za -QIfdiv- -Gs -YX-Zm300 -Ogtyb1 -DALTAIR -DNDEBUG -DWIN32 -DPC -DOS_WIN -D_MBCS -DLITTLE_ENDIAN_MACHINE -DHMDEBUG -DMSVC -DNT -DWINNT -DNO_DTORS -D_WINDOWS -DPC -D_X86_ -DAS_COMPRESSION

and options

cl -nologo -c -Fowin32/advfrnt.o -FRwin32/advfrnt.sbr -MD -O2 -GS- -W3 -GR -EHsc -FC -DIFORTRAN -Za -Gs - -Zm300 -Ogtyb1 -DALTAIR -DNDEBUG -D_SECURE_SCL=0 -DWIN32 -DOS_WIN -D_MBCS -DLITTLE_ENDIAN_MACHINE /wd4996 -DNHMDEBUG -DMSVC -DNT -DWINNT -DNO_DTORS -D_WINDOWS -DPC -DWINVER=0x0501 -D_WIN32_WINDOWS=0x0501 -D_X86_ -DAS_COMPRESSION -DDGFI_IMPORT

for 2005.

Is there any option in 2005 compiler that could decrease perfomance

Thanks in advance,

Victor

Thank you very much for answer. I will try to recompile code without YX and FR options.

My question was about the performance of the generated code.

Victor

Are there any options that could affect the performance of the generated code

Thanks,

Victor

Although it would appear that your code is set to -MD, it might be worth looking over this thread as well: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=128907&SiteID=1

beyond that it's difficult to know without having an example of code that is running at different speeds.
