I have a samba share running on my server (just an Intel N100 Mini PC). It’s running Fedora Atomic and my desktop is also running Fedora Atomic.
While it’s good enough to watch videos on, reliability when it comes to uploading files to it has been very poor. The connection ends up timing out after a few minutes of uploading.
I found that using rsync to upload files to it has been a lot more reliable.
Rsync will always be faster than SMB. NFS will be faster than both other options. It’s a protocol thing. You should tune your SMB config properly though, as there are tweaks that can benefit throughput greatly.
