Whoops, I was comparing the wrong numbers. Sorry.

All it says is that 8.0 performs better on the AMD for the reasons I specified.

Windows is running the show. VFP runs because Windows allows it. VFP still must process any Windows messages it receives during the iteration.

>To me does not interest if P4 or AMD is faster.

It's the reason why 8.0 performs better on the AMD. That was your question, and I answered it.

>I think the problem is on C++ 7.0 compiler.

The compiler doesn't target a specific CPU. It targets a specific CPU standard. It's the CPU, not the compiler.
