The ramdisk solution provided a 10% instant speed boost, you might want to think about creating a new config option that makes dolphin read the whole image into the memory instead of reading it from the disk.
Dolphin currently does disc reads on the same thread as all CPU emulation, so waiting for reads to finish unfortunately blocks a lot of other things from executing. To get rid of that problem, I've been working on moving disc reads to a separate thread: https://github.com/dolphin-emu/dolphin/pull/2149
It should be fast enough to make disc reads non-noticeable without the drawbacks of reading the whole image into memory (like increased startup times and increased RAM usage), but it hasn't been tested much yet.
