CAll vs SWITCH

dimon · July 25, 2012

I quote from the article Code Optimisation:

If Else If Else If Else ...
If you can't escape this using a switch control structure, then try and rethink the functionality. Especially if only one option is needed to match.

On the other hand switch is slower than if then else. To keep tidiness of the switch and speed of if, use if exitWith combined with call:
call {
if (cond1) exitWith {//code 1};
if (cond2) exitWith {//code 2};
if (cond3) exitWith {//code 3};
//default code
};

All right...

	private '_condition';
_condition=10;
switch (true) do
{
	case (_condition == 1):{};
	case (_condition == 2):{};
	case (_condition == 3):{};
	case (_condition == 4):{};
	case (_condition == 5):{};
	case (_condition == 6):{};
	case (_condition == 7):{};
	case (_condition == 8):{};
	case (_condition == 9):{};
	case (_condition == 10):{};
};

... will be slower than

	private '_condition';
_condition=10;
call {
	if (_condition==1) exitwith {};
	if (_condition==2) exitwith {};
	if (_condition==3) exitwith {};
	if (_condition==4) exitwith {};
	if (_condition==5) exitwith {};
	if (_condition==6) exitwith {};
	if (_condition==7) exitwith {};
	if (_condition==8) exitwith {};
	if (_condition==9) exitwith {};
	if (_condition==10) exitwith {};
};

But not everything is so simple....

	private '_condition';
_condition=10;
 switch (_condition) do
{
	case 1:{};
	case 2:{};
	case 3:{};
	case 4:{};
	case 5:{};
	case 6:{};
	case 7:{};
	case 8:{};
	case 9:{};
	case 10:{};
};

In order to compare something you have to have same or similar conditions, like in first 2 examples, 3rd example is different because it does not even check for booleans.

But they solve one problem?

In general, such "code optimization" is bullshit. Use whatever is *more readable*, or feels better to you. Then stick to it.

I, for one, like the switch(true)-thingy very much. :D

I highly doubt you could measure a significant difference in "performance" (with a resolution of 1ms anyways...). And even if, unless you're doing such a switch a gazillion times inside a loop or something, you really do not need to worry about such things. It will be fine.

P.S. diag_tickTime exists. Go ahead, have fun ;)

Sorry but if you want to compare command vs command without knowing task at hand, you create similar conditions, if you want to optimise a particular problem solving then you do just that:

In general "code optimization" does not mean "optimised for reading"

In general, such "code optimization" is bullshit. Use whatever is *more readable*, or feels better to you. Then stick to it.
I, for one, like the switch(true)-thingy very much. :D

I highly doubt you could measure a significant difference in "performance" (with a resolution of 1ms anyways...). And even if, unless you're doing such a switch a gazillion times inside a loop or something, you really do not need to worry about such things. It will be fine.

P.S. diag_tickTime exists. Go ahead, have fun ;)

Have to agree with your first line, to an extent. Reminds me of the health supplements industry. Might make 2-3% improvement over the long run, but cost a fortune, in our case, time instead of money.

Again, you seem to fail to grasp the idea of comparison of different commands, you have to put commands in similar conditions. The equivalent construct in this case would be

[color="#FF8040"][color="#1874CD"]_condition[/color] [color="#8B3E2F"][b]=[/b][/color] [color="#7A7A7A"]"zzzzzzzzzzzz"[/color][color="#8B3E2F"][b];[/b][/color]

In general "code optimization" does not mean "optimised for reading"

That's not what I've ment. Nice, readable code is more important (in the long run anyways, and hey; it's ArmA we're talking about!) than a "faster" switch. Because that switch is most likely fast enough already/not a bottleneck. And if you're going to rewrite that switch-statement, maybe do some measurings first to see where your work is needed most. Otherwise you're just wasting your time.

Sure, if you're going to call that switch each frame, maybe multiple times even, we can talk about it (again, maybe try to measure it), ;). Otherwise, or in general, I wouldn't suggest to write such a call thingy that relies on find/linear search (natively implemented) just to gain a bunch of microseconds (or what?). Plus it's a lot less general, than a switch(true)-statement, where you can put any conditions/expressions you like. Find doesn't exactly work like that (granted, that call/exitWith-construct isn't too bad).

Plus: your example really looks like you want to use a hash-table/a dictionary/err... an assoc. array :wave: as a datastructure anyways. So there is no need to compare this to a switch statement. And then, maybe use a proper hash/dictionary ds, right. Then you're back(?) up to speed, and it will read nicely too! :)

Btw., I've just seen that you've got a really nice blog going over there. Keep it up! You're showing some really nice things (that uav-pip-laptop is amazing! :yay: ).

While entering the game, with more than 200 online players, the server plenty of time become microseconds to seconds. And any important optimization: how to approach writing and reading speed of the code.

Again, you seem to fail to grasp the idea of comparison of different commands, you have to put commands in similar conditions. The equivalent construct in this case would be

However switch is still slower than:

Thank you for giving me a lesson at how to write code. FYI the array construct, despite scary looking, is almost 2 times faster than switch. So maybe you should run some speed comparison before slagging other peoples code next time.

I'm curious to know why switch is so slow in the first place. Surely if all these other methods are faster then its implementation could be improved?

Pretty sure it can be improved, lets hope there is a dev @ BI that is also optimisation fan.

Well, sure. You're pretty much comparing a natively implemented linear search (find) to a linear search implemented in sqf.

This thing here:

_condition = "zzzzzzzzzzzz";
_arr = [
"aaaaaaaaaaaa",{},
"bbbbbbbbbbbb",{},
//...
"zzzzzzzzzzzz",{}
];
call (_arr select ((_arr find _condition) + 1));

...should (or can) be written as:

_key = "zzzzzzzzzzzz";
[] call ([_arr, _key] call ASSOC_ARRAY_get);

...or something.

Wouldn't you agree?

Thank you for giving me a lesson at how to write code.

uhhm.., you're welcome? :sigh:
