macOS 上的 SMB 速度非常慢

Question

由于我最近买了一台新的 Mac Pro（运行 Catalina 10.15.2），我使用 10 GBit 以太网将它连接到我的 Debian 10 / Proxmox 服务器。

但是，当连接到共享时，我只能获得 150-300 MB/s 的读/写性能。

这是我当前的 smb.conf：

[global]         
    netbios name = server         
    realm = MY.DOMAIN         
    security = ADS
    workgroup = MYDOMAIN

    wins server = my.domain.test

    winbind enum users = Yes
    winbind enum groups = Yes
    winbind use default domain = Yes
    winbind refresh tickets = Yes
    winbind nested groups = No


    idmap config MYDOMAIN:backend = ad
    idmap config MYDOMAIN:schema_mode = rfc2307
    idmap config MYDOMAIN:range = 10000-20000

    log file = /var/log/samba/log.%m
    log level = 1 
    printcap name = /etc/printcap
    load printers = no
    username map = etc/samba/user.map
    vfs objects = recycle acl_xattr catia fruit streams_xattr
    map acl inherit = yes
    store dos attributes = yes   
    oplocks = no

    # Enable the recycle bin
    recycle:repository = /tank/storage/.recycle/%U
    recycle:touch = Yes
    recycle:keeptree = Yes
    recycle:versions = Yes
    recycle:noversions = *.tmp,*.temp,*.o,*.obj,*.TMP,*.TEMP
    recycle:exclude = *.tmp,*.temp,*.o,*.obj,*.TMP,*.TEMP
    recycle:excludedir = /recycle,/tmp,/temp,/TMP,/TEMP

    # Apple
    fruit:aapl = yes
    fruit:encoding = native
    fruit:locking = none
    fruit:metadata = stream
    fruit:resource = file


[share1]         
    path = /tank/share1
    read only = no       
    valid users = @"MYDOMAIN\share1-Access"
[share2]
    path = /tank/share2
    read only = no
    valid users = @"MYDOMAIN\share2-Access"
[timemachine]
    path = /tank/timemachine
    read only = no
    valid users = @"MYDOMAIN\timemachine-Access"
    oplocks = no
    fruit:aapl = yes
    fruit:time machine = yes
[downloads]
    path = /tank/downloads
    read only = no
    valid users = @"MYDOMAIN\downloads-Acccess"
[cloud-backup]
    path = /tank/cloud-backup
    read only = no
    writeable = yes
    valid users = @"MYDOMAIN\cloud-backup-Access"

SMB 在 Mac 上的表现非常糟糕，而且一直如此。我的建议：不要担心，只需安装 netatalk 即可；您将毫无问题地获得 1GB/s 的速度。或者使用NFS，也能达到1GB/s没有任何问题。然而 Netatalk 是最安全的选择，一些应用程序可能通过 NFS 表现奇怪。另外，Netatalk 在身份验证、文件权限等方面的行为与 Samba 一致。

我什至使用“Hackintoshes”比较了性能：运行 Windows 的同一台机器通过 SMB 达到 900MB/s，但作为 Mac 运行时达到 250MB/s；但通过 Appleshare 可以达到 1GB/s。
