Subject: Sftp slow on both our centos installs
The short version.
Copying over SFTP to our centos boxes maxes out at 2MB a sec.
The Question:
Is there some sort of speed limitation somewhere in the ssh/sftp daemon?
Does anyone have any idea why this could be happening?
The long version
We have centos 4.6 installed on 2 different machines, different
hardware, different nics. Even on 2 different subnets.
I've tried different switches, 1000 Full/Half 100 Full/Half and still
get the same speed. It maxes out at 2MB a sec.
Same switch, network, client using sftp to our xserves gets 10MB a sec.
Basically filling the pipe of the network.
The only thing that is the same on both the linux boxes is the distro.
So i thought maybe someone may have come across this before.
I haven't tried other protocols yet (FTP and HTTP) I'll check that
tomorrow.
Thanks,
Jamie

You mentioned you tried different switch speeds/duplexes. You didn't
mention if you tried manually setting the speed/duplex on the NIC's
rather than use auto-negotiate. If you have the ethtools package
installed, and type "ethtool eth0" what is the speed/duplex set to? Does
it match what you have set on the switch? If not, try forcing eth0 (or
whatever your NIC is) to the speed/duplex you have on your switch and
are cabled up for. (e.g. in /etc/sysconfig/network-scripts/ifcfg-eth0 we
have: ETHTOOL_OPTS="speed 100 duplex full autoneg off" )
