cocos2d-x v4.0 Performance issue on Android vs 3.17.1

[SeptemHuang]

• cocos2d-x version: v4.0、v3.17
• devices test on: HUAWEI P20
• developing environments
• NDK version: 16b

Steps to Reproduce:

1. add sprite and label x 1000 in scene let the draw call reach 1000 more
2. run or not runAction is no different

v4 fps much lower than v3.17

Could you attach code to reproduce an issue?

Could you attach code to reproduce an issue?

here

auto scene = Scene::create();
auto layer = Layer::create();
layer->setPosition(Director::getInstance()->getVisibleOrigin());
scene->addChild(layer);

auto visibleSize = Director::getInstance()->getVisibleSize();


for (int i=0 ; i<3000 ; i++)
{

    Sprite *sprite = Sprite::createWithSpriteFrameName("test.png");
    sprite->setPosition(Vec2(random(0, (int)visibleSize.width), random(0, (int)visibleSize.height)));
    sprite->setScale(0.5);
    layer->addChild(sprite);

    Label *label = Label::createWithSystemFont(StringUtils::format("%d", i), "Arial", 15);
    sprite->addChild(label);
}


Director::getInstance()->runWithScene(scene);

Yeah, the code is some thing just like that Make the draw call higher will easier to see the fps drop in v4

No, I start to doubt the cocos2d team was gave up to maintain cocos2dx.

No, I start to doubt the cocos2d team was gave up to maintain cocos2dx. you maybe right, the official team has given up the cocos2dx project, it is a pity
