Overview

Make huge ChatGPT chats feel light again.
GPT Performance Optimizer prevents the page from choking on thousands of messages. It renders only the most recent messages by default and lets you reveal older ones when you actually need them.

🟢This is an open-source extension: https://github.com/sergey-pimenov/gpt_performance_optimizer

⚠️ When you reveal hidden messages, they’re shown in a simplified form. Some features may be limited. If you’re missing something you need, email me at pimenov.web@gmail.com and I’ll do my best to add it.
⚠️ Due to technical reasons (on ChatGPT’s side), it doesn’t work in ‘share’ chats such as https://chatgpt.com/share/*

What it does:
⦿ Shows just the latest part of a long chat so the page stays fast and responsive.
⦿ Adds a slim toolbar with Show +10, Show all, and quick-navigation controls.
⦿ Reveals older messages on demand without reloading the page.
⦿ No accounts, no setup — just install and use.
