Need some DSP LLE help (Slow framerate)

[Caboose]

I know this has probably been brought up many times, and usually it's because the person doesn't have a strong enough computer.

My computer has handled anything Ive thrown at it; oddly this is a challenge for it.

Im trying to set up configurations for DSP LLE for Paper Mario: The thousand year door.
every configuration I've tried has failed, I'm sure there's something I'm missing.

My specs:
Windows 7 64-bit
AMD Phenom II Black edition 955 Quad core 3.22 Ghz
AMD Radeon HD6950 2gig
4Gb Dual channel, 2000mhz nb frequency, DDR3 RAM
Using Dolphin 3.0-555

I just want to have smooth framerates, and audio that wont cut out, or just stop.

I'll accept any and every bit of advice. Thanks.

EDIT:
