1.
The initial flush of a SharedObject is sometimes slow depending on size.
Later flushes are pretty quick, but multiples are slow. Therefore, your use
of _global to hold them is good.
As long as you save the data on slots, this is better than deeply nested
objects (at least for Flashcom). I'm not sure the same holds true here.
Like, a slot is a propery on the data object.
var so = SharedObject.getLocal("prefs", "http://www.server.com/");
so.data.slot1 = "some value";
so.data.slot2 = 3;
In Flashcom, if a slot's data changes, only that slot is updated, and not
the whole shared object. Since local shared objects work similiary, I
usually create my SO's the same way, but because all your doing is reading
and writing, I don't think it really makes a difference. The only reason I
even mention it is the fact that if it's designed that way on Flashcom, then
there may be some speed or benefit to using slots instead of:
so.data.slot1 = {};
so.data.slot1.value1 = "asdr";
so.data.slot1.value2 = "asdf";
Notice, we're only using one slot, but putting a deeply nested object on it.
I think that is bad, but I still do it...
At any rate, 1.

Hello All,
I am building a desktop app that needs to save variables for use immediately
in the current session and also in later sessions, using shared objects. The
variable's value may change several times during one session and will need
to be updated immediatly in the movie.
Have a question though, Which yields the best (fastest) performance? 1.
Store all the user's info as global variables, then save them to the hard
drive all at once.
2. Keep saving and retrieving the variables as shared objects (if user
changes mind and chooses red instead of green, shared object would update
immediately and be retrieved by current playing movie)
3. I'm totally missing the boat, and you guys can tell me how you would do
this : )
