Ultra-Fast Telegram Userbot

I am building a claim-style userbot that must beat roughly forty competing bots in the same Telegram channel. Using Telethon with raw MTProto, I need a solution that:

• Opens and maintains a single Telegram client session on Linux.
• Listens to channel traffic in real time and reacts to every new message the moment it arrives—in practice, I’m aiming for sub-second latency measured from server receipt to callback press.
• Immediately clicks the first available inline callback button associated with that message.
• Provides a simple way for me to adjust the target channel, keyword filters (if any) and the exact callback index without digging through code.

I will consider the project complete when the script consistently triggers before the majority of other claim bots in a live test and the logs confirm no missed messages during an extended run.

Deliverables
1. Well-commented Python script (Telethon + any low-level MTProto tweaks you require).
2. A requirements.txt or Poetry file.
3. Setup & run guide for Ubuntu 22.04.

If you have previous benchmark figures or can suggest further optimisations—asyncio tweaks, custom transport layers, direct DC connections, etc.—let me know.
