Generally for a laptop (which i'm assuming your computer is) you can go into the BIOS to change a few settings. Usually you can push the DEL key when booting up to go into the BIOS (although it may be a different key). In the BIOS, usually under the advanced settings area, you can often increase the speed of the FSB, or set it to a "turbo" mode.
If I were you I'd highly recommend looking in there to see if you can adjust anything. Otherwise I'm not sure you are going to get the greatest of speeds with a Dual Core 2.0ghz cpu.
To give you an example, I'm running a Q6600 (thats a quad core) at 3.4ghz, and theres occassions in a few wii games where even this CPU cant maintain a steady 60 fps.
In Mario Kart Wii, I can barely manage 30 fps sometimes.
Also, you appear to be running in 32 bit mode, correct? It shows JIT32 on your Dolphin Status bar.
Your CPU supports 64 bit mode. You should be running a 64 bit version of Dolphin, not 32 bit.
