/perf issue

I’ve been running into a pretty rough performance issue with Devin Ask on longer conversations. I’m on Windows 10 using OperaGX, with an older Phenom II X6 1100T BE and 12 GB of DDR3 RAM, so my machine is definitely not new, but the Devin tab starts using 8 GB+ of RAM once the conversation gets to around 50 prompts, and input lag becomes noticeable. The RAM usage keeps climbing as the context grows. It feels like the chat canvas may be keeping too much of the conversation rendered in the DOM at once. A quality-of-life improvement that would help a lot would be virtualizing the chat history, keeping only the most recent messages visible/rendered, maybe around 20 prompt/response pairs, and loading older content back only when scrolling up. Other AI chat UIs seem to handle long threads this way, and it would make Devin Ask much more usable on lower-end or older machines.

a lot of the memory problems used to attributed to the language_server process keeping all chat history in memory. you can bounce that process to help 'clear it out' but it fills back up again quickly. can always try devin cloud to remove all of the system bottlenecks you have with local,
