Dual Opteron is 35% sneller bij mysql applicaties.
In the extensive benchmark tests under Linux Enterprise Server 8 (32-bit as well as 64-bit), the AMD Opteron made a good impression. Especially in the server disciplines, the benchmarks (MySQL, Whetstone, ARC 2D, NPB, etc.) show quite clearly that the Dual Opteron puts the Dual Xeon in its place.
