AMDX2 3800+ (Fedora Core 5) STD CRC SLICE8 CRC 8192 bytes 8.576635 7.170038 1024 bytes 1.504361 1.402446 64 bytes 0.154459 0.144209 Odd that the AMD shows opposite of the two Intel numbers above, and that it was an "Intel engineer" who wrote it. My first speculation is that you did your Intel numbers backwards. My second speculation is that you already thought of that and confirmed before posting. :-) So yeah - not too impressive...
