Re: Samba Performance

Fri Oct 25, 2013 6:03 pm

I have a raspberry model b with 512 mb of ram with raspbian. I made all the updates.

I attached to raspberry a wifi adapter and a 1.5 tb hd powered with ext4 partition. I can't try to plug in ethernet, because the router has the only ethernet port connected to the modem.

transfer with samba is slow. a few minutes ago I added

Code: Select all

socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF = 65535 SO_SNDBUF = 65535
and now to copy a file on the PC connected to the network, the transfer rate varies from 100 kb / s to 900 kb / s.
before it was fixed to 200 kb / s and a few minutes later the transfer was interrupted.

screenshot of my transfer rate:
1) https://dl.dropboxusercontent.com/u/107 ... /rasp1.png
2) https://dl.dropboxusercontent.com/u/107 ... /rasp2.png

I have these lines in smb.conf:

Code: Select all

[shared]
comment = HD Raspberry
path = / mnt / nas
public = yes
guest ok = yes
writable = yes
socket options = TCP_NODELAY IPTOS_LOWDELAY  SO_RCVBUF = 65535 SO_SNDBUF = 65535
and my /etc/fstab is:

Code: Select all

proc                         /proc                   proc    defaults          0       0
/dev/mmcblk0p1  /boot                    vfat    defaults          0       2
/dev/mmcblk0p2  /                            ext4    defaults,noatime  0       1
/dev/sda2              /mnt/nas              ext4    rw,auto,users     0       0
/dev/sda1             /mnt/USB_1500  ntfs-3g  rw,auto,users     0       0

I'd like to get to speed as 3 mb / s to watch film in streaming with VLC or to copy file from hd on my pc or mac.

can you help me please? you need more information?

that's not about samba... but file system in general:

ntfs-3g:
dd if=/dev/zero of=/mnt/HD/test.tmp bs=500K count=1024
1024+0 records in
1024+0 records out
524288000 bytes (524 MB) copied, 507.767 s, 1.0 MB/s

ext4:
dd of=/media/HD/test.tmp if=/dev/zero bs=500K count=1024
1024+0 records in
1024+0 records out
524288000 bytes (524 MB) copied, 21.4531 s, 24.4 MB/s



ntfs uses CPU... soo... sucks for devices like raspberry!

Re: Samba Performance

Thu Dec 05, 2013 1:22 am

I have RPi v2 (512MB RAM) with Rasbian out of the box and Samba + all updates.
I have 64GB USB 2 Stick on powered USB Hub.
RPi connected to Virgin Media SuperHub via ENET and Windows 7 System connected via .11n WiFi

Already added:
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF = 65535 SO_SNDBUF = 65535

I am getting 4.5MB/s MAX read from Pi to PC. Pi Share is Read-Only (so my kids don't delete stuff)
I am sure I can get better than this but I don't know where the lag is.

dd test from the stick runs at ~20MB/s so the USB access isn't an issue.
CPU Usage during transfer only hits 40% so I don't think this is the bottle-neck.
My WiFi is super-fast with everything else although I don't have another NAS to compare it to.
USB Stick is FAT32 formatted.

I have read through the thread and see so many widely varying results. It is totally usable for my purposes but it isn't fast enough for video over the network as playback is choppy. I guess I just want to know if it is worth chasing a few extra MB/s or where to start looking.

Re: Samba Performance

Tue Jan 14, 2014 10:22 am

Hi guys,

I still don't get the performance some of you are getting. I have connected a 3TB WD Elements ext3 drive (almost empty) and are copying from a windows machine over 100Mbit/s network.

I've added the

Code: Select all

socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65535 SO_SNDBUF=65535
to my smb.conf

The benchmark on the hard drive shows speeds up to 22MB/s. My Pi is clocked at 900MHz. CPU is constantly at 100% with smbd at the top.

Any advise?

Hi All,

Just checking in here. I think the problem is my WiFi location/performance. With the same setup in other parts of the house it's a lot better. I haven't clocked the speeds but one of my kids was streaming video to an iOS device while another copied a video to his Android tablet without disruption. I need to extend my WiFi reach to better service my home office.

Although I did not performed tests with Samba share, it seems the speed is significantly higher with EXT4.

PS. My main concern was that whenever I has heavy access to NTFS, I saw very high CPU usage with ntfs3g library. With EXT4, I completely uninstalled it. Now the highest CPU usage goes to the actual processing applications (like PHP, srync...)

Re: Samba Performance

Theres a fix you can put in samba conf, I got off google. I have not tried yet but I post it here, It goes @ the bottom of samba.conf. Global Section.

max xmit = 65535

socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=65535 SO_RCVBUF=65535

read raw = yes

write raw = yes

max connections = 65535

max open files = 65535

sudo service samba restart

sudo /etc/init.d/samba restart

Tue Mar 11, 2014 1:39 pm

I've been looking into this for a bit in the past days.

Default values for max xmit = 65536, for read/write raw = yes. So explicitly setting these probably won't change a thing.
According to the samba people the SO_SNDBUF and SO_RCVBUF are something to experiment with. Higher isn't neccesarily better. (source)

I'm struggeling to get read performance higher than 4mb/s with modest overclock and samba cpu usage in the 90+%. The external drive performs just fine with 25mb/s read speeds.

Planning to do an iperf test between my windows 7 machine and the pi tonight to if link speed could be the issue.

I would really like to be able to stream high quality video with samba. So I'm still hoping for a magic option or some UDP based streaming solution. (Tried VLC but its performance is even worse).

Is the external drive formatted EXT4 or some other format?

It's ext4 mounted with defaults,noatime.

Ok even with the pi under stress from another process the iperf test shows the network seems to be fine:

A iperf link speed of 47 megabits/sec is maybe not what we want or expect, but it's what it is (mine is actually lower .... )

This link speed translates to roughly 5 Megabytes / second.
This is with no optimizations in iperf.

The throughput if I copy some media files from my Raspberry Pi to my Windows 7 PC is about 6-6.5 megabytes/second. Perhaps windows does some optimization? With my mac I sometimes reach speeds up to 7.5 megabytes/second, but not always.

4 Megabytes/second should be enough bandwidth for most media files (blueray excluded).

Hi,

I have OMV (openMediaVault) running and get an amazing ;) speed of 0.6 MB/s. Here's how I tested:

Code: Select all

dd count=100 bs=1M if=/dev/urandom of=/media/bla/test
100+0 records in
100+0 records out
104857600 bytes (105 MB) copied, 169.511 s, 619 kB/s
currently, the hub between the raspi and the 2,5" hdd EXT4 is not powered by an extended power supply, but the hdd has additional USB power from another external source.

any ideas how to improve this setup?


update: I just added the mighty line

Code: Select all

socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF = 65535 SO_SNDBUF = 65535
to smb.conf - and the speed dropped to truly exciting 62KB/s . OMG, omv!

Try connecting the HDD directly to the rpi and not through the hub.

Re: Samba Performance

Mon Mar 31, 2014 1:54 pm

Out of curiosity what is open media vault? I can only assume it's either a DLNA server or a file sharing mechanism like Samba. If it's DLNA have you tried other DLNA servers to see if you get better throughput? If it's just a file sharing mechanism is there a reason why you don't want to use samba?

I use an old model B (one of the 256 boards from back in the day) as a dedicated Samba server. Every so often I reinstall Raspbian from scratch, install Samba and enable my share. Without any additional tweaking to samba or overclocking to the pi, I get very reliable speeds of 7.5 MB/s all day long provided my laptop is physically wired into the network, using WiFi it's more like 2-3 MB/s, but that's a limitation of the router I'm using more so than the Pi.

Beyond that +1 to tbar suggestion of connecting the hard drive directly to the Pi. There a lot of detailed (boring) and technical issues for doing this concerning the way Linux handles the USB stack and the way the Pi's USB port operates, but the long and short is you'll get better performance with the Hard Drive directly connected to the Pi.

I oddly enough tend to get better writes than reads, about ~10 write and around ~7 read, on a wired network, ext4 formatted drive.

        panic action = /usr/share/samba/panic-action %d
        idmap config * : backend = tdb
        use sendfile = Yes
        write cache size = 131072
I have tried various variables and some made it drop to speeds below 100kB/s. This seems to be best config for me.

@abishur

OpenMedia Vault is a very stable and easy to maintain NAS solution. The successor of FreeNas and can be found at http://www.openmediavault.org/ or http://sourceforge.net/projects/openmediavault/

Since october 2011 I've got it running on an old P-4 box with multiple 2TB disks in a raid configuration.

Ohhhhh, so how many hard drives do you have connected to the Pi and which RAID configuration are you using with it?

Well, sorry for the misunderstanding, but OMV isn't running on a Pi, but on a Pentium-4 with 4 2TB SATA disks in RAID5.

ha! Sorry, I thought you were the individual who posted above about the OMV with really slow speeds, but after scrolling back up I see that it was huedrant with those issues. Sorry about that! :lol:

Hi,

Having the same speed issues as all of you (except some lucky ones) I decided to run some tests. I also read some incorrect methods so I'm gonna try and be precise on those.

All tests were run with the following configs :
- RPi B 512, XBian rc1,

Code: Select all

gpu_mem_512=256, arm_freq=840, sdram_freq=450, core_freq=400
in config.txt and

Code: Select all

socket options = TCP_NODELAY SO_RCVBUF=65535 SO_SNDBUF=65535
in samba.conf (ran though

Code: Select all

testparm
)
- MacBookPro 2.9Ghz, Mavericks 10.9.2 native, Windows 7 under VirtualBox with NAT networking, 1GBps (wired) and 144MBps (wireless) connectivity
- test file: test.mp4 ( 417MB )
- test drive: 3,5" 500GB Sata over USB (has its own power cable), ext4

First: usb speed tests

Code: Select all

 Device | R/W |  bs  | count | Speed (MBps)
--------+-----+------+-------+-------------
  zero  |  W  | 500K | 1024  | 16.4
  zero  |  W  |  4M  |  128  | 18.4   
 random |  W  | 500K | 1024  |  9.6
 random |  W  |  4M  |  128  |  9.9
  null  |  R  | 500K | 1024  | 21.7
  null  |  R  |  4M  |  128  | 21.9
Conclusions concerning write speed tests:
- using /dev/random is creating a bottleneck
- using bigger blocks is better


Second: SMB speed tests

Code: Select all

Wired | OS  | R/W | Speed min-max (MBps)
------+-----+-----+---------------------
  NO  |  X  |  W  |     2.6 - 3.2
 YES  |  X  |  W  |     3.4 - 4.2
  NO  |  X  |  R  |     3.6 - 4.5
 YES  |  X  |  R  |     6.1 - 6.7
  NO  |  W  |  W  |     4.3 - 4.8
 YES  |  W  |  W  |     3.7 - 4.5
  NO  |  W  |  R  |     6.0 - 6.9
 YES  |  W  |  R  |     6.4 - 7.1
Conclusions:
- OSX SMB support could be better and suffers from wireless connections
- Windows SMB support works OK on wireless connections

Having also tried VFAT (FAT32) filesystem I guarantee, though not obvious, ext4 is way better. I also found this article concerning FS speed tests on Linux: http://www.ilsistemista.net/index.php/l ... ml?start=4
It show that ext4 and ext3 share basically the same speeds.

In my case I think the major bottleneck is OSX SMB support, and maybe overclocking a bit more the Pi could also help.

For those having 10MB read speed just a quick question: you're testing with windows right ?

I hope this can help, Stan

I get around 10-11 on Writes And 7-8 on reads on a wired network with all Windows 7-8 PCs, on a 256 Pi running Raspian, can't remember the GPU split, I know the GPU side is low.

Externally powered Seagate 3TB Hard drive is ext4 and the Samba share is public, anyone can read or write (its at my apartment, could care less about the security).

Don't ask why Writes are better than Reads, I have no idea why.

How do you measure this? 11MByte per second is near the theoretical limit, what a 100MB-network can give?
My Reading-Speed is the same as you posted, and sometimes I also see a Writing-Speed, which is a very little bit higher than for reading, but in none case such a big difference?
A: What does the command 'cat /dev/urandom', can you tell me please?
B: Yeah, that's very simple: It feeds your cat with radioactive material!

Its what Windows 8 tells me when I transfer large files to my NasPi
