What's the latency for receiving messages compared to telethon

[cuiliubi]

The message delay on Telethon seems to originate from Telegram. I tested my own group and found that the delay of my group is very small, less than one second, while the delay of other groups is between 0.5 and 2 seconds. If you have a better answer, please share it with me
