Hi,
I am transferring files to a Solaris 10 installation on Sun Fire 480.
I find that when transferring large files > 1G via FTP, the performance is < 2GB. I am using FileZilla and the network is 100Mbit.
I am currently transferring 2 files concurrently & there are only having a bandwidth of 400+KiB/s each.
I do not have the same issue when transferring to other linux based servers (Intel x86-84).
Any ideas how I can improve the performance?
Thanks,
Raymond
I've had a similar problem in Linux (proftpd), by default there is a setting in FTP server config that limits the speed.
Hi orange47,
Do you remember what's the setting?
Thanks,
Raymond
from what?
We've had trouble with what was termed a packet shaper I think. It's basically something that has rules to ensure everyone gets a fair deal on the network, but it means large transfers take longer. There may be more to this than simply my two servers do thing a bit oddly.
There is always a reason, but finding it may take a long time.

What are your TCP settings on the Solaris server? As root, run this from a sh/bash shell:
for parm in `ndd /dev/tcp \? | awk '{ print $1 }'`; do
echo -n $parm": "
ndd /dev/tcp $parm
done
and
for dev in /dev/net/*; do
for parm in `ndd $dev \? | awk '{ print $1 }' | grep -v '?'`; do
echo -n $dev: $parm:" "
ndd $dev $parm
done
done
Also, what's the output from "ifconfig -a"?

My system doesn't have the /dev/net/ directory.
And "ifconfig -a" gives:
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000

inet xxx.xxx.9.25 netmask ffff0000 broadcast xxx.xxx.255.255
ether 0:14:4f:39:83:25
I have masked the network part of the IP address with xxx.xxx. In this case xxx.xxx.9.25 is the Sun server & xxx.xxx.9.207 is the Windows client.
Thanks,

Hi orange47,
I am not sure which ftp daemon I was using. When I issue a "svcs -a | grep ftp", I get:
online 15:23:20 svc:/network/ftp:default
I am trying using sftp connection but the throughput is still the same.
"ps -ef | grep ftp" gives:
root 1668 1663 0 08:33:14 ? 0:00 /usr/lib/ssh/sftp-server
root 1681 1671 0 08:33:36 ? 0:12 /usr/lib/ssh/sftp-server
root 1682 1673 0 08:33:36 ? 0:11 /usr/lib/ssh/sftp-server
So I am thinking the problem may not be with the FTP daemon but more on the network side.
Thanks,
Raymond

Hi hicksd8,
I am transferring file from a Windows 7 PC using FileZilla version 3.9.0.2 64bit.
Thanks,
Raymond
---------- Post updated at 09:12 AM ---------- Previous update was at 09:05 AM ----------
Hi rbatte1,
We don't have any equipment/hardware between the client & the server except a 100Mb switch. I have also make sured that ipfilter is disabled on the Sun machine. And the client doesn't face the same issue when transferring files to other Linux servers. So I think we can rule this part out unless there is some other filtering on Solaris that I don't know about.
I would agree that this could potentially be both difficult & time consuming to diagnose & resolve.
Thanks,
Raymond
Hi hicksd8,
I did another test: ftping the same file of about 1.7GB from the same windows client using the same FileZilla to the Sun Solaris server in question and to a Linux server.
The average throughput to the Sun machine is about 1MiB/s.
The average throughput to the Linux machine is about 10MiB/s.
So it's not windows that is in question here.
Okay. Can you try ftp from the Linux box to the Sun box just to prove that the Sun box is not capable of receiving data at high rate. Try the Linux box initiating the transfer (ftp put) and the Sun box initiating the transfer (ftp get).
Also, can you tell us what NIC's are in the Windows, Linux and Solaris boxes? Not so much the make/model but the speeds. The problems I was eluding to in my previous (now removed) post only seems to occur with gigabit cards.
You can try:
ndd -set /dev/tcp tcp_max_buf 2097152
ndd -set /dev/tcp tcp_xmit_hiwat 1048576
ndd -set /dev/tcp tcp_recv_hiwat 1048576
ndd -set /dev/tcp tcp_cwnd_max 1048576
If that doesn't work, try this, especially if the FTP from the Linux box works at "normal" speed:
ndd -set /dev/tcp tcp_slow_start_initial 2
Because it is quite possible Windows is the problem here.
Hi,
Today, transferring from windows to Solaris the throughput is about 1.3MiB/s.
This is true before & after:
ndd -set /dev/tcp tcp_max_buf 2097152
ndd -set /dev/tcp tcp_xmit_hiwat 1048576
ndd -set /dev/tcp tcp_recv_hiwat 1048576
ndd -set /dev/tcp tcp_cwnd_max 1048576
Transferring from Linux to Solaris has a speed of about 1.2+MB/s using lftp.
Ftp get on Solaris from Linux has a speed of about 1.7+MB/s using sftp.
After this:
ndd -set /dev/tcp tcp_slow_start_initial 2
The speed from Windows is about 1.5MiB/s.
One thing I noticed is that when transferring 2 files, the files have a speed of about 1.3MiB/s each but when one is done, the other's speed didn't increase.
This is also true for adding a new file transfer, the speed of the first one didn't decrease.
It looks very much like a per "channel" limit.
Thanks,
Raymond
Everything is just so slow then.
What network switch(es) have you got in between this lot?
What device(s) do you have at /dev/ce and /dev/ce0?
What's the output from
for dev in /dev/ce*; do
for parm in `ndd $dev \? | awk '{ print $1 }' | grep -v '?'`; do
echo -n $dev: $parm:" "
ndd $dev $parm
done
done
You may need to run
ndd -set /dev/ce instance 0
if there's no /dev/ce0 and just one /dev/ce device.
Also, what's in your ce.conf file? It's probably somewhere under /kernel or /platform:
find /kernel /platform -name ce.conf
Also, what's the performance if you FTP to/from localhost on the Solaris server?
Hi hicksd8,
Sorry for the late update.
We have DLink Gbit switches in between.
Windows client <---> DLink Gb switch <---> DLink Gb switch <---> server
The linux machine is also on the same path.
Thanks,
Raymond

Any chance of eliminating the two d-links from this? Are the machines close enough to use a crossover cable for example?
Print Page - Poor performance on gigabit Network
I know that mis-configuration could be causing this but I think it unlikely from the Solaris side. That O/S runs large corporations and banks all around the planet and won't be bugged in network performance.
As you can tell I'm still believing that Solaris is not the problem here.
Will get back after I try out the direct link.
