Hi, I’m new here. I also have both Rock64 4GB and Rock64 2GB. I noticed, that this incredible performance `Single thread SHA256 performance is 672 MB/s using minio/sha256-simd (462 MB/s using crypto/sha256)` only achieved when using syncthing binaries compiled for `aarch64`. The `armhf` variant on the other hand gives very poor results: `Single thread SHA256 performance is 18 MB/s using crypto/sha256 (18 MB/s using minio/sha256-simd).` I tested using debian stretch and 0.14.45 release binaries.
