IIRC, VPS represents the amount of frame render requests the emulated CPU sends to the emulated GPU in Dolphin. FPS represents the amount of frames that are actually rendered.
It sounds like your game is a 30 FPS game running at half-speed. Dolphin displays a percentage that represents the game speed, and it's accurate in most cases (using the VBeam Trick creates a notable exception).
EDIT: nvm, can't read on my tiny iPod screen lol. Your hardware is way too low to adequately play Dolphin (specifically the CPU) at least for whatever game you're trying to play. Which game is it btw? Turbo boosting might help; try to keep your laptop as cool as possible when running Dolphin.
