+Removing in-tree cryptography: GnuTLS 3.4.7 required
+----------------------------------------------------
Samba is making efforts to remove in-tree cryptographic functionality,
and to instead rely on externally maintained libraries. To this end,
headers at build time) for all configurations, not just the Samba AD
DC.
+Thanks to this work Samba no longer ships an in-tree DES
+implementation and on GnuTLS 3.6.5 or later Samba will include no
+in-tree cryptography other than the MD4 hash and that
+implemented in our copy of Heimdal.

Using GnuTLS for SMB3 encryption you will notice huge performance and copy
speed improvements. Tests with the CIFS Kernel client from Linux Kernel 5.3
show a 3x speed improvement for writing and a 2.5x speed improvement for reads!
