Need to optimize flash 9

I've been using flash 8 and 9 for some simple Multi touch drawing board application and realised that it is running too slow and requires a very fast computer to run it. Therefore, the need to optimize the code. I quick search on the internet led me to the following tips:

1) Declare local variables instead of global variables. (i had the impression that global variables just take up ram but will run faster during runtime. But i guess i'm wrong)

function doSomething() { var mx = 100 var my = 100 var ar = new Array()...}

2) Using OnEnterFrame, it is not recomended to attach too many event handlers all over the movie clip because this can lead to spaghetti code and also it can significantly degrade performance.
Most of the times using one single onEnterFrame can be a good solution: just one main loop that takes care of the various operations to carry on.

3) 25-35fps. The higher the fps the slower it will run the code.

4) Visibility. One of the best solutions to this problem is to have an empty frame in your movieclips where you can gotoAndStop(), freeing up some work to the flash player.

_visible = false; doesn't work.

5) for in loop instead of the usual for or while syntax.

for (var i in arr) {  if (arr[i] > 50)  {   // do some processing here  } } 

is faster than 

for (var i=0; i<10000;> 50)  {   // do some processing here  } } 
//------------------------------------------------------------------------
var i=-1 while (++i <>
is faster than 
for (var i=0; i<1000;>
//-----------------------------------------
6) _global vars is faster than Timeline vars. 
7) Multiple var declaration is faster than single
8) Var name lookup
t = getTimer() var floor = Math.floor var ceil  = Math.ceil for (var i=0; i < num =" floor(MAX)">
is better than 
for (var i=0; i < num =" Math.floor(MAX)">
9) Short var names is better than long variable names
10) Declaring var in loops (to the contrary) is faster than declaring before a loop.
11) using single if statements is faster than complex conditional expressions in a single if statement.
12) Nested loops, while loop is faster than for loops (eg for 2D data) 
13) TellTarget vs dot syntax. 
tellTarget(mc){
_x =10;
_y = 10
} 
is faster than mc._x = 10; mc._y = 10;
14) Loop listening for pressed keys
if(Key.isDown(Key.LEFT)) 
use 
keyDown = Key.isDown
if(keyDown){}
instead. 
15) use int() instead of Math.Floor()
16) Often performance is about perception. 
If you attempt to perform too much work in a single frame, 
Flash doesn't have time to render the Stage, 
and the user perceives a slowdown. 
If you break up the amount of work being performed into smaller chunks, 
Flash can refresh the Stage at the prescribed frame rate, 
and there is no perceived slowdown.

The paradigm shift

There is no more hope, its just a recurring nightmare like one of those where you keep running away from someone or something.

Generation Boom to Generation X

A generation gap between the Generation X and Y and their Baby Boomer parents is common around the world. Every country, every state, every village, has its own culture, set of rules and beliefs. In particular, why are people from the Generation X so miserable in Singapore? Everyone has something to complain about with it comes to family, marriage, bgr for the Generation X. Where most if not all should have started their own families, why is there a large number of divorced and single or unhappily married Gen X people out there?

New technology, political differences, workplace behavior, age of consent, age of responsibility, education system etc are blamed for the different and confusing generation gap from just one generation away. The boomers and the gen X. The Gen X is way past the age of MTV, WWE, Rock n Roll, and Retro. But the expectations of our other halves are worlds apart from those of our parents. Blame it on our education? our teachers? our British english with American TV? A pretty messed up society I would say. The age of Housewives and breadwinner's pride, to a neverending fight for equality in certain things in life, but in truth, the man has to suffer more, serve the woman, give in to her, open the door, who invented the gentleman? but it only exists in the era of slavery and monarchy. With the current democracy, the women's charter is obsolete unless there is an equal men's charter with women earning as much as men. Multi-tasking between a women's server, house-husband, a career-minded man, fillial son without compromising his own interests seems like mission impossible.

However, many still make it with the help of their understanding parents giving way, proper management of bosses, spouse and kids. But if any one of these factors were to be missing, the man's entire life would crash. Something will have to be given up, be it career, marriage, or family. but why is it that the women do not have this problem? They are traditionally not expected to stay with the family after marriage. So they have it easy. What happened to the rest of the traditions where the women have to serve the men? take care of the house and the family? In a company, different people fill different roles and never is there an accountant doing an engineer's job or a CEO taking minutes of a meeting. But even the CEO himself, is supposed to "take minutes" and open the car door for his gf and pay for the meals and movie (hold the popcorns too).

Watching the movie wildhogs, the man finally becomes the man when he silences his noisy wife who scolds him everyday and asks for her to "feel" him. Does it have to come to an ultimatum before the woman knows there's only this much a man can take and suffer before giving in? Or is it just these small group of unhappy people, single, divorced people, have this problem?
