Sending/Forwarding messages to large groups can take minutes.. why????

[idan-dagan-imagenai]

Is there an existing issue for this?

• I have searched the existing issues.

Is this a problem caused by your code, or is it specifically because of the library?

• I have double-checked my code carefully.

Describe the bug.

I am trying to send messages to large groups I have (Around 900 participants in each group).. sometimes it can take minutes. I don't get it. I am running on linux server inside docker, using LocalAuth to store chrome data, and this is my puppteer config:
puppeteer: {
headless: true,
args: [
'--no-sandbox',
'--disable-setuid-sandbox',
'--disable-dev-shm-usage',
'--disable-gpu',
'--no-first-run',
'--no-zygote',

      '--disable-accelerated-2d-canvas',
      '--disable-extensions',
      
      '--disable-background-timer-throttling',
      '--disable-backgrounding-occluded-windows',
      '--disable-renderer-backgrounding',
  ],
  executablePath: process.env.CHROME_BIN || '/usr/bin/chromium-browser'

}

Expected Behavior

I expected a message to take a few seconds.. max. what am i doing wrong? I am using whatsapp web js latest version.. those are my dependencies:
"dependencies": {
"cors": "^2.8.5",
"dotenv": "^16.4.5",
"express": "^4.19.2",
"express-rate-limit": "^7.4.0",
"joi": "^17.13.3",
"morgan": "^1.10.0",
"multer": "^2.0.0-alpha.7",
"proxy-chain": "^2.6.0",
"puppeteer": "^24.30.0",
"qrcode": "^1.5.3",
"qrcode-terminal": "^0.12.0",
"whatsapp-web.js": "^1.34.2"

I check my internet speed - it is good. i also checked sending messages to small groups - also works great. what can i do guys? please assist.
