[gentoo-user] interconnecting speeds

[Paul Stear]

I am copying files from my gentoo box to an xp box and it is so slow.  I have 
both boxes connected with cable via a router, which connects to my broadband 
isp.
When downloading from the internet to either box I get fast speeds in the 
100's of MBs.  However transferring box to box I only get about 1MBs.
Are there any setting I should look at to enable faster transfers?

What software are you using (client x server)? What is the method of
transfer (HTTP, FTP, SFTP, NFS, SAMBA)? Sorry, but your message say
almost nothing, and makes it quite hard to help.

Sorry, I am using samba and kde and am copying files from a directory on the 
gentoo box to smb://<my xp box>/my directory using konqueror.
What other information can I supply?

Do you have any antivirus running that could be scanning all the files
transfered? I cannot think of another reason for such a difference
between your LAN and Internet transfer speeds. Try another protocol
(HTTP, FTP) and check speed, if its still slow, its probably something
on your XP box, if its fast, then you can check samba configuration.

Anyway, disable any antivirus/firewall and try again.

Are you sure it's actually slow or are you just looking at the number 
thinking it's slow...
If you are getting "fast speeds in the 100's of MBs" from the internet 
then I want your internet connection. it's probably more like 100's of KB...
Regardless, only 1MB across LAN is still slow.

How are you measuring the speed of your connection?

I take it that this is a conventional smb setup, not some ssh or vpn tunneled 
deal?

PS. I'm on a 1Mb/s adsl connection (or around 125KB/s).  If you're getting 
100's of MB/s download rate you're either somewhere in South Korea, or you're 
on some sort of an fiberoptic backbone, or you're using satellite?

Try different cables.
I've had situtations where traffic in one direction is "fast", the other 
pitifully slow.

Yes it is just very slow, the mesage stalled keeps coming up and then starts 
again.
It seems as if the lan when transferring between computers is using 10 and the 
internet is using 100. Both lan cards are 10:100 cards.  Does this make 
sense?
I will try again and disable virus protection on the xp box to see if that has 
any effect.

Unless it's actually a 10Mb/s HD connection.

Double check what the connection speed is for XP.  You can do the same
using ethtool under Linux.  You should see 100mbit, full duplex on
both.

One problem could be if you have flaky cables, the switch or the NICs
could attempt to re-negotiate the link speed frequently, and kill your
bandwidth.

So I would try different cables, or maybe even pick up an inexpensive
ethernet switch (not "hub"!), and see if that makes a difference.
Maybe it is a problem with the switch in the router...

Thanks Richard,
My gentoo box is set ok using ethtool. How do I check the setting on the 
windows xp box?
Downloading files from the internet on windows is as fast as my gentoo box, 
the problem seems to be when they are talking to each other.

If the connection has a tray icon, double-clicking that should bring up
an info dialog that has the link speed somewhere. Otherwise you'll have
to click you way through control panel->network->blah, I don't know
exactly...Windoze config is a maze of twisty little passages, all alike.
Another thing: check the Linux side with ifconfig, it gives some
statistics on errors, dropped packets and overruns next to RX and TX
packet counts. Those should be zero, or at most pretty small numbers. If
they are not, your cables and/or switch are flaky.
