My company is in the position of having to upgrade soon, because of the abysmally broken SMB stack on everything since Mavericks. It's fine when you are doing SMB between Macs. But against Windows servers with decent sized directories (upwards of 10K folders), it's a nightmare. Unbearably slow, beachball city, missing files and folders that show up just fine on Windows. We use Acronis Connect (formerly ExtremeZIP) for AFP connectivity at present, but that only helps with the missing files problem. It's still painfully slow. SMB on 10.13.2 is blazingly fast, almost as fast as Windows, and the missing files/folders problem is gone.
