Optimisation for speed usually starts by finding the code that is most
sluggish. You can spend a very long time optimising by doint things
like replacing for loops with do loops or whatever for marginal
improvement when some other simple change, like replacing extensive
use of += to concatenate strings with Array.join or just plain +
(specific to IE), can have a dramatic effect.

You might also consider whehter your effects add to the functionality
of the page or are just a nusance.
