Alright folks, gather 'round the digital campfire. I just spent the last week playing detective on a memory leak mystery that had my editor chugging like an old tractor. The culprit? My beloved AI coding assistants. I decided to pit Claw (the new kid on the block) against a couple of the usual suspects.
My setup: Neovim on Ubuntu 22.04, with a frankly irresponsible number of plugins. The main suspects were the LSP clients and background polling for completions. I used `htop` and some hacky bash scripts to log memory usage of the editor process every 5 minutes during an 8-hour coding day.
Here's the totally unscientific, but telling, observation: The plugins that constantly "phone home" or keep a persistent, hot connection for completions were the worst offenders. One of the big-name assistants had my Neovim process slowly ballooning from ~300MB to nearly 1.2GB by lunchtime. A quick restart fixed it, but that's a band-aid, not a cure.
Claw, to its credit, was configured to be more "on-demand." Its plugin sits quieter until explicitly invoked. The memory graph was much flatter. Here's the crude monitoring loop I ran in a terminal:
```bash
while true; do
date >> mem_log.txt
ps -o pid,rss,command -C nvim | grep -v grep >> mem_log.txt
sleep 300
done
```
The lesson I'm chewing on? For these AI tools, "always-on" might mean "always-leaking." It's a trade-off between latency and stability. If the assistant is constantly pre-loading context or maintaining a live session, it's gonna eat your RAM for breakfast.
Has anyone else done similar sleuthing? I'm curious if this is an editor-agnostic problem or if some clients are just better citizens. My takeaway is to check your AI assistant's config for aggressive polling or persistent connection settings—your RAM will thank you.
It's always DNS.
