Speed of GameCache vs Global Lists

[Korolen]

Well, the title says it all =p.

I've done some searching on this topic, but did not find anything, and I was wondering if anyone had done some speed tests on these two meathods.

Ank'e much,
Korolen

I am positive that Globals would be faster. I think.

I shall do some testing, though it's logical that Globals are faster, but I have seen wackier things happen with WC3's engine...

 

[wonderpriest]

Okay. I did a bit of testing, and as I expected Globals are much faster that using the Game cache. Actually, about 7 times faster

The game cache is a great resource to use, but don't try to replace Globals with it, or depending on the trigger actions, you will notice the difference. So, first try to use locals, then globals, then the cache

gamecache isn't so slow...but you should use globals if you can.
why are you asking this btw? plain curiosity or are you trying to do something?

 

[Korolen]

I just want to optimise a 33 times per second trigger (for sliding), which currently uses all gamecache.

Thanks alot for the testing, I should be able to make my triggers much faster. (By the way, how did you get your results?)

 

[SFilip]

if you're using CSCache or kattana's vars in it then there probably isn't a way to use globals. besides if your trigger works correctly then there is nothing to worry about...

Well, it works, I just want it to be as fast as possible, and it should be easy to convert to globals.

Ooops. I meant 4 times faster, I use the numpad and pressed the wrong key. It's actually a bit less than 4, but I rounded up, and I admit, I didn't do alot of testing. Used a loop with some random actions inside, that were exactly the same for both. After thinking about it, I believe that retrieving a value from the cache is not that much slower than retrieving a value from a variable. It's just that it takes extra time to access, set equal to itself plus one, because you have to save a value that you just retrieved.

Wow, I just made that more complicated than it need to be...

To make it simple:
Using game cache is only slower because you have to access and manipulate it more, which adds more and more time.

Use Globals when you can, after locals, and before the game cache.

well unless its working slow then you really shouldn't. besides its not even possible if you are using H2I (the bug used in kattana's vars and CSCache) - that function is slower than storing in either gamecache or globals so it makes no difference really.

H2I isn't that slow. Game cache is, and can be avoided, such as with a parallel array system.

 

[wonderpriest]

Yes it is

parallel array system

A nice big one

 

[Korolen]

Well, in the map that I'm currently developing, each player only controls one unit, so I don't need H2I to do a global array, or to use GameCache (but the whole advantage of GameCache is that you CAN use H2I easily).

And, as for optimising the function, It may not make my computer run slowly, but I know for a fact (my brother's computer in mind) that there are some people who play Warcraft on slooooow computers, and I want it to run wiht the best framerate as possible.

And wonderpriest, how did you do your speed tests? I can't figure out a way to acuratly record time, and when I do anything that takes some time (like running tests in a loop), then the trigger is cut short.

then why CSCache uses the gamecache? if globals are faster then i see no point in that...
