Sorry, I found the problem!
Where I remap the view
if(!mmFile.MapViewOfFile(FILE_MAP_WRITE, 0, bytesWrittenInView, bytesToMap)
I position the view wrongly. Instead of bytesWrittenInView, it should be 
totalBytes written. Sorry for that..

Can confirm that Memory mapped files are much faster than regular file I/O..
