Ok Thx for Suggestion Wrathion.
I have tested performance on my other project: its Epic size map, full terrrain, 1200 Doodads, 83 units total, but around 200 units are spawned during play.
I was using knockback system, was creating 2 point leaks per 0.05 second, thats 40 per second at minimum. Im saying at minimum because i was also creating some leaks with projectile throwing and spells but these was minor, it was some point leaks and some unit group leaks.
How test looked?:
Well as i said i created standart knockback system with timer set to 0.05 ticking 20 times per second, then i removed custom call to allow 2 point unit leaks per 1 tick, then i have esc key attached to jump key, so im just jumping with me hero around the map, this map is epic sized has shops, and spawns like Dota so there is even combat. Then i bought some shurikens and was throwing shurikens, shurikens are also attached to knockback system with additional collision detection. To shorten it: I created AT LEAST 40 leaks per sec.
The results were quite interesting even for me: After 4: 19 (game time) i quit because i was bored as hell and my finger hurt from pressing ESC and sometimes watching fighting, buying item or casting a hero spell to notice some lags.
Nothing Happened, not even a single slowdown or single lag.
Hope that after this test you have no doubt about performance, i can calculate how much time of leaks in this map is worth 4:19 of non stop leaks, but i estimate thats over 2 hours, if you are still not sure about performance i will calculate it and determine exact time. (as I said i had no patience to wait, but until 4:19 not even a single lag or slowdown, ot would maybe last even 20 mins. Who knows? )
