How to start Forwarder Telegram correctly?

Question

Python

I'm using phyton 3.9.6 . I'll
attach the code here so that you can get acquainted in more detail, in order to get an answer / help from you on this topic.

Help me figure it out, the reason is that ... when I launch more than 10 resenders, the telegram stops sending, or sends with delays.

Maybe you have some simpler code written that will make this job easier. GOD GIVE YOU HEALTH. YOUR HELP IS REALLY NEEDED. (P.S. If I'm not a proger, I'm trying to learn and understand what is necessary for work.)

I'm sure you understand this better and I hope for your help. (My telegram is for every firefighter @Mr.Nike , I’m ready to pay some kind of cape for human help)

Config (text.doc)

api_hash = ........... (Api hash of telegram account)
username = .............. (Nick/Subject)
dst_channel = https://t.me/ ...................... (message delivery.Where)
src_channel0 = https://t.me/ ............ .....(Getting message.From)
src_channel1 = https://t.me/ .................(Getting message.From)
