[Samba] samba-tool slow operations

Using samba-tool in our old server (that has Zentyal managing samba),
returns 'normal' (fast) results, but running samba-tool in our new
installed samba returns 'slow' results.
time samba-tool ou list
ldb_wrap open of secrets.ldb
OU=Domain Controllers

real    0m0,330s
user    0m0,262s
sys     0m0,068s

New manually installed samba server:
time samba-tool ou list
OU=Domain Controllers

real    0m7,383s
user    0m6,886s
sys     0m0,489s

Why is this happening and how can I solve this?

new server smb.conf
       bind interfaces only = Yes
       dns forwarder = <our-running-dns-ip>
       interfaces = lo ens3
       passdb backend = samba_dsdb
       realm = <realm.ext>
       server role = active directory domain controller
       workgroup = MULTILAB
       rpc_server:tcpip = no
       rpc_daemon:spoolssd = embedded
       rpc_server:spoolss = embedded
       rpc_server:winreg = embedded
       rpc_server:ntsvcs = embedded
       rpc_server:eventlog = embedded
       rpc_server:srvsvc = embedded
       rpc_server:svcctl = embedded
       rpc_server:default = external
       winbindd:use external pipes = true
       idmap config * : backend = tdb
       map archive = No
       vfs objects = dfs_samba4 acl_xattr

       path = /var/lib/samba/sysvol
       read only = No

       path = /var/lib/samba/sysvol/cl.ibilce.unesp.br/scripts
       read only = No

Thanks for any advice.
