Re: Samba Performance problem

Well this might sound a bit dumb, but...

Here is the whole setup.

I have a G wireless network with 2 users.
I have a P4 with 1GB of RAM running as the core server and I also use it to "play/experiment" with Xen.

Right now I have the Xen HV as samba server as well. Besides that is running a 128MB, 2GB disk space virtual that runs dhcp and dns internally.
This machine is wired to the Wireless switch at 100Mbps.

I've been monitoring the traffic with iftop to check the speed on the transfer and is below my worst expectations.
Right now I have a peak  of 673Kb while trying to watch a movie.

Previous setup with Centos gave me a throughput of 42Mb.

The Samba version that I'm running right now is 3.3.13 and here is my smb.conf

    netbios aliases = MEDIALAB
    security = user
    socket options = TCP_NODELAY  SO_SNDBUF=8192 SO_RCVBUF=8192
    use sendfile = true
    local master = yes
    os level = 33
    wins support = yes
    comment = Home Directories
    browseable = no
    writable = yes
         comment= Musica para alegrar la vida
         path = /media/external/Multimedia/Musica
         public = no
         writable = no
         write list = @wheel
         browsable = yes

         comment= Algunas pelis para entretenerse
         path = /media/external/Multimedia/Peliculas
         public = no
         writable = no
         write list = @wheel
         browsable = yes

I've seen the same, but others told me they could not reproduce it, so I always
blamed it on a local setup error - would be interesting to find out now ;-)

What do you use to test the performance?

In my case it seemed read-mostly workloads do pretty fine, but writing is
realy slow.
