[gentoo-user] NIC setup? slow transfer speed

[gentoo-user] NIC setup? slow transfer speed

[Stuart Howard]

Hi

I have a home LAN with a mix of dual boot, XP and Gentoo[<-- mine].
Now the basic problem is this :-
Transfer of file [eg. 200Mb]
Dual boot on XP    --  XP  speed approx 50Mbps
Dual boot on linux    --  XP  speed <= 1Mbps

Now this applies regardless of transport ie. I have tried smb FTP NFS,
I have been tweaking the smb performance which did improve it though
not beyond the figures above
http://www.dd.iij4u.or.jp/~okuyamak/Documents/tuning.english.html

However I cannot believe that this is the best that can be acheieved
ie. it would not be acceptable in an enterprise environment yet smb
servers are used with windows clients in such places so

my question is, where am I not looking?
Could it be the nic driver?
or setup of same ?
or something obvious I am not looking at?

Any pointers at places of investigation are welcome.

I have read somewhere that this might be caused by slightly different
mru/mtu settings between your "linux" and "XP" computers. If you had
that second comp dual-bootable, I bet you would not get 1Mbps between
linux-linux...

How are you measuring this?  My first suspicion is that you are
measuring on your machine and trying to compare the figures from
different tools running on different OS's.


You also dont say what type of network this is over - 10/100/1000 ??
Also what hardware and drivers?

I agree in that I am using whichever tool is available to measure the
speed  eg. konqueror file transfer dialog or bmon to monitor rate
however I am not talking optmisations here where the same tool would
be necessary
eg. win to lin 39Mb file > 6 minites
win to win 39Mb file <20 seconds all on same hardware and network

The network itself comprises 10/100 nic's and a linksys WAG54G
gateway/router which again is 10/100.

resolution

[Stuart Howard]

OK well I give up

Situation :-

Transfer 39Mb file from
gentoo -> XP share using Konqueror trans time <=25 seconds [XP share
mounted smb using Linneibourhood]

Transfer 39Mb file from
gentoo -> XP share using winXP copy trans time >=5 mins [gentoo smb
directory to XP share dir ie. XP shared dir Not mounted]

So this is same file moving from same computer to same computer over
same network with NO changes except that "pushing" the file from linux
is massively quicker than "calling" the file from win.
I realise that there is probably a valid technical explanation for
this behaviour that is Beyond Our Level Of Current Knowledge [Sir]
however should it really be so hard to do this for an average user?

stu

ps. Solution is simple send letter bomb to M$ though it may take a
long while to get there unless I use a m$ proprietory letter carrier.

pps. Apologies if I am using this list for my rant, it was valid
untill this last post. It ends here

Re: [gentoo-user] NIC setup? slow transfer speed

[Steven Susbauer]

I've had similar problems quite a bit. After a while I just installed 
pure-ftpd on Gentoo and used smart ftp on Windows. It still took a long 
time but seemed to go much faster than that smb stuff.

I have a similar situation here, but with an additional interesting
observation. If I copy a file from WinXP to an SMB share on a Gentoo
server with the XP explorer, I get about 2MB/s throughput, which is not
all too much on a 100Mb/s network. However, if I run the following
command in the background (eth0 being the interface over which I copy):

  tcpdump -n -i eth0 >/dev/null

the throughput increases to about 8-10MB/s!

I have no idea where this could come from. The only explanation I can
see is that tcpdump puts eth0 into a sort of promiscuous mode, which
interacts favorably in the SMB protocol. But I haven't been able to
figure out how I should tune eth0 to get the same results without tcpdump.
