The speedup is caused by the new cryptography extensions that are part of ARMv8 (aarch64). When Syncthing is compiled for ARMv7 (armhf), they are not used.
Yeah, use the one actually compiled for your CPU. The openssl benchmark looks the same as ours, judging by ours being single thread (as mentioned) and openssl getting
@bizarre87 Do you have any actual performance numbers for the RK3328 when transferring files? I keep wondering how fast it is with a USB3 disk…
I have tried plugging in both SSD via USB, WD RED 3TB drive and also WD My Book DUO RAID1. Using through Plugable USB 3.0 Hard Drive Dock. The maximum speed I have seen during transfer hovers around 15-28MBps with spinning drives and 40+ MBps with SSD. iMAC is a peer device, both running the latest versions of syncthing.
In comparison, AFP transfer between iMAC and rock64 reaches 920Mbps.
If there is a more scientific way to run transfer speed benchmarks, let me know.
