Hello, @2372281891! Thanks for the report.
Marking this as help wanted—I'd appreciate it if someone could run tests using Go's memory profiler to help identify whether there's a memory leak and/or determine which data structures consume the most memory.

I agree. I hope it can be reduced soon.

To whoever decides to take this up in the future:
Here's a memory profile of Zen after initialization with the filter lists (click on the image to get the full view):

The vast majority is consumed by our primary data structures, ruletree and node, which represent the filter list rules as a trie. They're far from being written in a memory-efficient manner, so there's a potential for improvement.

I am working on this issue on a fork https://github.com/ilovelinabell/zen-desktop but how did you guys do the profiling? I think I have shrunk the mem usage a bit but want to quantitatively compare. If you guys can pull my branch and run the profiler, that could also be good. Thanks

@ilovelinabell Excited to see what comes out of it! The profiling can be done with Go's built-in pprof, this guide looks good enough to follow: https://www.codereliant.io/p/memory-leaks-with-pprof
