Description Bastien Nocera 2017-11-23 12:13:07 UTC
Using gvfs's smb backend, which uses libsmbclient, forcing encryption usage if available, the transfer speed reduces from around 26-27 MB/s to around 8-9 MB/s.

Is this a server, or a client problem, or a mix of both?

Both.

Samba 4.7 supports aes hardware encryption on intel compatible hardware.
configure supports --accel-aes=intelaesni

That helps a fair bit, it's a shame my server doesn't have any acceleration code available though.
