Hii :) Just as friendly reminder… Don’t put a LVM system on an old Raspberry pi 3B+ !! I solved the issue when putting everything on a simple EXT4 filesystem. Now I’m able to download, upload, check integrity and resolve DNS without it giving a sweat.
I think (I will not dive this rabbit hole right now haha) it’s only related to the pi 3 archtitectur (shared USB bus with the ethernet controller?).
Yeah it probably added a lot of overhead and I/O bottleneck due not beeing optimized for it. But I’m not sure this is applicable in a more conventional setup !
I have an older laptop (+/- 10 years old) which run nicely with LVM-ext4 and does not hang or choks on piHole + qbittorrent in a similar setup.
Guess, I have to keep it simple on my pi 3, But happy it works as expected now !
