我是 django 频道的新手，我根据 django 频道文档创建了一个聊天应用程序，并且成功创建了它。但是当我的频道数量增加到 200 多个（意味着 200 人在不同的房间聊天）时，服务器开始变慢，我们可以说它停止响应。在这种情况下请帮助我。

在此处输入代码

#setting.py 文件

CHANNEL_LAYERS = {    'default': {    'BACKEND':
    'channels_redis.core.RedisChannelLayer',    'CONFIG': {"hosts":
    [('127.0.0.1', 6379)],
        },
        },
        } 
CHANNEL_LAYERS = {
        "default": {
        "BACKEND": "channels.layers.InMemoryChannelLayer"    } }
    
    
    
    
# chat/consumers.py
import json
from asgiref.sync import async_to_sync 
from channels.generic.websocket import AsyncWebsocketConsumer 
from chat.models import Room count=0 
class ChatConsumer(AsyncWebsocketConsumer):
    async def connect(self):
        self.room_name = self.scope['url_route']['kwargs']['room_name']
        self.room_group_name = 'chat_%s' % self.room_name
    
         # Join room group
         await self.channel_layer.group_add(
                self.room_group_name,
                self.channel_name
          )
    
          await self.accept()
    
        async def disconnect(self, close_code):
            # Leave room group
            await self.channel_layer.group_discard(
            self.room_group_name,
            self.channel_name
            )
    
    
        # Receive message from WebSocket
    async def receive(self, text_data):
        text_data_json = json.loads(text_data)
        message = text_data_json
    
        # Send message to room group
        await self.channel_layer.group_send(
        self.room_group_name,
        {
        'type': 'chat_message',
        'message': message
         }
         )
    
    
    
    
        # Receive message from room group
    async def chat_message(self, event):
        message = event['message']
    
        # Send message to WebSocket
        await self.send(text_data=json.dumps({
        'message': message
         }))
