I am not aware that there is any Compiz[-Fusion] module that deals with menus. 
If you point me to one, I guess I would probably be able to point you to some 
settings in that module that control animation speed. But this is just 
academic, AFAIK. My point was that animations in general can be made 
arbitrarily fast so that they don't get in your way. If you feel that anything 
is slowing you down, and there is no slider somewhere to speed it up, you can 
always disable that particular effect.

What is certainly *not* true is the statement that *all* eye-candy effects 
necessarily slow you down.

> e.g. Open menu, instantly pick choice,

Umm, that would be --- open menu, find the choice, navigate the mouse pointer 
to it, click on it. Now, it takes at least one second to navigate the mouse 
pointer to anything (of that size) on the screen. Ditto for arrow keys. So if 
you make the effect last for a 1/4 of a second, it will be over well before you 
reach the choice with the pointer.

Oh, you are saying it takes time for the menu to be displayed so you can 
_read_ it? Sure, in that sense yes, it does slow you down --- it adds, say, 
additional 250ms (which should be configurable) to a typical 2-second operation 
(read, navigate, click). If this additional quarter of a second is too 
expensive, maybe you shouldn't be browsing the menus with a mouse in the first 
place?

Using the menus is slow by definition. If you want speed, use hotkeys. That is, 
if you know the combination. If not, you are likely to be slow with the menu 
both with and without eye-candy stuff.

> The effects are *NOT* that quick that they add insubstantial delays.

Every effect in Compiz that I ever tried (of course I haven't tried everything) 
had its speed configurable, "instant" (ie. no effect) being typically the 
fastest choice available. Further, most of the effects time can be configured up 
to a millisecond. So I would say each of them *can* be configured to be below 
anyone's personal threshold. If you find some effect whose speed cannot be 
configured, feel free to file a RFE against it, or just turn it off.

But this is all aside of the main point. Eye-candy effects exist so that you 
can *enjoy* them, not to get on your nerves. I simply enjoy watching it 
happen, and sometimes I deliberately configure things to be slow. When I get 
bored of it, I speed animations up again or disable them completely.

Think of it as a stress-relief utility. :-) It is decoration on the screen, 
much like pictures on the walls in your home. Its main point is to cheer you 
up and make you feel more pleasant when using a computer. If it gets on your 
nerves, don't use it.

Best, :-)
