FPS issues

Any help here would be great.

My game is dropping down to 2 FPS with very little happening. My PC is i7, 8GB Ram and 1GB GFX Card. And my Android Device is a Dual Core 1GB processor.

However when I run the game on both machines the games FPS falls to the point the game breaks.

This a link to the stats.

This is the script that each object is running which does not seem like it would cause problems. One the game gets to approx 20 objects its slowing down, by mid 30's unplayable.
