I'm very much interested in core 2 duo performance and would appreciate hearing what others have experienced in this regard. I don't know what OS you use, but here are my experiences so far with Linux:
You seem to have exactly the same processor as I have access to. And I get much better performance than you. Maybe it comes from the system: - which compiler do you use? - which libc do you use? - what is your "-march" option and -O ? I use g++ 4.1.1, -march=opteron, -O3, and quite recent linux installation (Mandriva 2007). For me also, everything is in 32bits and I did not optimize further for this processor. Maybe changing these things would explain the difference between the performance I get and you get. (should be > 2. for you). Sylvain
