Well, here's the thing when it comes to Dolphin: it requires strong single-core speeds in CPUs. Unfortunately, the AMD APU and FX series chips are not very strong in this regard. They're about as strong as second generation Intel i-series chips.
There are some things you can do to max out what performance you have:
1) Update drivers, Windows updates, DirectX Web updater, and latest version of Visual C++
2) Make sure under Power Management in Windows you're running in High Performance. Also, make sure you have a high performance profile set in Catalyst Control Center so that it isn't using the integrated graphics chip in your APU, but instead your high performance card (the drop-down window in Dolphin doesn't always work the best)
3) Use the OpenGL backend on one of the latest dev builds, as it is faster than D3D.
4) Switch back to the JIT recompiler. It's faster.
5) See if you have a motherboard that is capable of overclocking. If so, crank it the juice to get some extra speed.
