Why is the smb transfer performance much lower than the ftp performance? I am connected to WiFi 5g, in the same point and I am trying to transfer the same file using the two different protocols, at different times. There is nothing else that is using the network. The file I am transferring is present in the ssd connected to the USB 3.0 port of the beryl.
Is there any procedure to speed up the samba protocol?
At first you are comparing the simple FTP with the more complex SMB protocol. In general the rabbit will always be faster than the turtle … but okay.
You are comparing FTP, written after a RFC and tested well, with SMB, written by a huge tech company and still ‘only’ some kind of reverse engineered, today.
I am not familiar with the OpenWRT implementation of SMB, but lets try a little in the [global] section of your smb.conf:
TCP_NODELAY- Maybe more packet drops at the destination, but also the resended packages will be faster.
IPTOS_LOWDELAY- the same, but for the transport.
SO_RCVBUF- Yeah, just try what are suitable values for your setup. Try not essential more than your OS can handle.
- does OpenWRT Samba knows
- Samba is using caching (the thing, that drives everybody insane while calculating the ETA for a download) … Mabe
Something like this should be the outcome:
[global] log level = 0 socket options = TCP_NODELAY IPTOS_LOWDELAY read raw = yes write raw = yes oplocks = yes max xmit = 65535 dead time = 15 getwd cache = yes lpq cache = 30 [some share] oplocks = no
But again, I’m not a samba expert, I try to avoid it, whenever possible,
This is the global section of my smb.conf file:
[global] netbios name = GL-MT1300 display charset = UTF-8 interfaces = lo br-lan server string = GL-MT1300-212 unix charset = UTF-8 workgroup = WORKGROUP browseable = yes deadtime = 30 domain master = yes encrypt passwords = true enable core files = no guest account = nobody guest ok = yes invalid users = root local master = yes load printers = no map to guest = Bad User max protocol = SMB2 min receivefile size = 16384 null passwords = yes obey pam restrictions = yes os level = 20 passdb backend = smbpasswd preferred master = yes printable = no security = share smb encrypt = disabled smb passwd file = /etc/samba/smbpasswd socket options = TCP_NODELAY IPTOS_LOWDELAY syslog = 2 use sendfile = yes writeable = yes
First can test in the PC samba client operate, may be the samba client APP read/write affect.
Also can config the /etc/samba/smb.conf.template
set the socket read/wrte cache size, as:
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536
read raw = yes
write raw = yes
large readwrite = yes
getwd cache = yes
write cache size = 262144
