I did a benchmark on linux and it is about 2% slower on my machine.

I created a new patch where I removed the stat call.
I now calculate the full path name on linux and windows.
This means that soft/hard links do not work any more.
There is still a small slowdown because we create/compare the full path 
name now.
But it is about 0.1% on my 64 bits x86_64 machine. Hard to measure correct.
