[bug]: Running LND becomes very slow on macOS (arm64) compared to Linux (ubuntu 22.04 aarch64)
Background
Recently, I've observed that running LND on macOS (M1 - arm64) is significantly slower compared to running it on Linux (Ubuntu 22.04 aarch64). Here are videos demonstrating the difference:

You can find the logs from both environments below:
Also here are the lnd and bitcoin configurations used for both the environments (the passwords included are just for testing):
- bitcoin.conf - Linux (Ubuntu 22.04 aarch64) - lnd.conf - Linux (Ubuntu 22.04 aarch64)
- bitcoin.conf - macOS (m1 arm64) - lnd.conf - macOS (m1 arm64)
Context
Both instances are connected to the same chain backend (Bitcoin Core). The tests appear to be independent of computing resources. The LND instance on macOS was a fresh start, but the slow runtime persisted even after multiple attempts (e.g., testing cache or other factors).
Your Environment
Ubuntu (Linux)
- Environment: Virtual machine using Multipass
- OS: Linux 5.15.0-102-generic - Ubuntu 22.04.4 LTS (Jammy Jellyfish)
- CPUs: 1
- RAM: ~2 GB
- Storage: ~39 GB
- LND Version: 0.17.99-beta (kvdb/v1.4.6-4-geadbfbe1e)
macOS
- Environment: Main host
- OS: Darwin 23.0.0
- CPUs: 8
- RAM: ~8 GB
- Storage: ~228 GB
- LND Version: 0.17.99-beta (kvdb/v1.4.6-9-gd4c193757)
Chain Backend
- Type: Bitcoin Core
- Version: v23.0.0
Expected Behavior
Both environments should have similar runtime performance.
Actual Behavior
The runtime on macOS (M1 - arm64) is significantly slower compared to Linux (Ubuntu 22.04 aarch64).
did "Siri" learn from this app?
Not sure I understand the context of this question!
I think this might be due to the FSYNC behavior of MacOS. See https://news.ycombinator.com/item?id=30370551.
