hickups and stutters in gameplay

hi,
Im keeping on top of file sizes and everything for best performance but im obviously doing something wrong i guess because straight away from the start of my gameplay scene its starts to stutter.
my game has two animated characters. one chasing the other. the character chasing YOU is moving up and down to avoid objects.. I used the interpolate behaviour for this. Is that maybe causing problems if its used about every 2 seconds?

This gets rid of the main constant timer action and limits it to just the timer in the interpolate function
Thanks
