I found out why ChatGPT gets slower the longer you use it and it has nothing to do with OpenAI's servers

Been frustrated with chatgpt freezing in long chats for months. thought it was a server issue. turns out it is not. Chatgpt renders every single message in your browser at once. a 300 message chat means your browser is juggling thousands of live dom elements simultaneously. the longer the chat the worse it gets until the tab freezes completely. I opened devtools and watched the memory climb with every new message. at around 200 messages my browser was using over 1gb of ram just for that one tab. Once i understood the problem i built a fix for myself.
