Question On Coding "Style" [FMX]

This is essentially a question for FMX but all flash applys really.

I have applied some code to a movie clip symbol, and used:

[AS]onClipEvent (enterFrame) { Do This a}[/AS]

then

[AS]onClipEvent (enterFrame) { Do This b}[/AS]

And used OnClipEvent (enterFrame) about 5 times in total - I did this so that it is easy to remove one of these commands if I want.

Obviously, I could include all of my OnClipEvent (enterFrame) actions into 1 OnClipEvent (enterFrame) separated by colons, like this:

[AS]onClipEvent (enterFrame) {
Do This a;
Do This b;
}
[/AS]

I am wondering if by using it 5 separate times I am causing flash to slow down a significant amount, or even at all.

Please let me know,
thx.
