Is there a way to fix a .5 Sec deley?

Theres a 0.5 sec delay on the Moving bricks and Lighting changes due to so many scripts running at one time any way to fix it or shorten the delay with out lowering the wait( ) time?

The only way I can think of without lowering wait() times is to take out/optimize your other scripts, however, I'm not the most experienced person so there may still be a way :)
