Hi,
We develop a new platform using WCE5.0. This platform is a test &
Measurement device. The software must process on a great amount of data.
This data cames from a custom device develop by us.

I need to know what is the difference (performance) between application
write using native code or manage code?

It is true that the performance of an application, using manage code,
dramatically drop when it communicate with a native code component?

Our driver to communicate with our hardware is a native code DLL. If the
caller application use manage code, does the performance drop too when it
doing call to the driver?

Thank you for advice
