What settings are you using specifically?

You should try:

1. Try the latest git build from the download page.

(under Graphics)
2. Set Rendering Mode to "Buffered rendering".
3. Set Render Resolution to 1x PSP.
4. Ste Display Resolution to 1x PSP.
5. Set Frameskipping to Off.
6. Set Alternate Speed to 0.
7. Disable "Retain changed textures".
8. Set Texture scaling - Upscale level to Off.
9. Make sure all settings under "Hack settings" are disabled.
10. Make sure "Software rendering" is disabled.

(under System)
11. Enable Fast memory.
12. Disable Multithreaded.
13. Disable Force real clock sync.
14. Set the "emulated PSP'c CPU clock" to 0.
15. Uncheck "Enable cheats".

If it still performs poorly, it may be worth checking your Android developer settings (do you have developer mode enabled?), and enabling the stats display to see what's going on. Or checking if anything comes through on adb logcat.
