I am trying to optimize software for Atom pc ,the performance is satisfactory for Intel i5 , but seventh time slower on Atom.
I am asking for any suggestions that may be helpful at this case.

I am woking with visual studio 2008 and Intel @ Composer XE 2011 compiler .I already tried to set the
/QxSSE3_ATOM option but got no difference in performance.

I downloaded the Embedded software development tool - trial version. But I don't know if that could be useful in my case and if it is ,what should I start from

Thanks ahead,
Larisa
