 Posted: Sun Sep 28, 2003 3:22 pm Post subject: Slow FTP Transfers on LAN |
 |
|
I'm using ncftp to transfer files between my Gateway (Linux) and my Windows 2003 Server installation. I can't reach speeds higher than 5mb/s
The computers are connected to eachother with regular TP cable with a 100mb Netgear switch.
The reason I'm using FTP for tranferring files instead of samba is that i just can't get samba to reach as high speeds as I can with ftp.
Here are some values for you to work with 
| Code: | /dev/hdb:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 14593/255/63, sectors = 234441648, start = 0

readonly = 0 (off)
readahead = 8 (on)

The connection to the LAN is on eth1 while the internetconnection houses on eth0 
| Code: | root@pr0nstar:/home/teddy# mii-tool
eth0: autonegotiation failed, link ok
eth1: negotiated 100baseTx-FD flow-control, link ok |
It bugs me I can't reach higher speeds. If I had another Windows installation this wouldn't be an issue :¨/
But since I hate Windows I really want to solve this 
Thank you in advance

first you can do an mii-tool on your eth0 card to get it working at 100M-FD (this could increase transfert rate)
first simply emerge it
and after you can see all supported mode on your network card by launching:
and then just type:
| Code: | | mii-tool -F 100baseTx-FD eth0 |
to get eth0 working in 100M-FD
hope that helps |

He is on 100M/FD. eth0 is the Internet connection, eth1 is his LAN connection. I doubt he is FTPing files across the Internet and expecting 100Mbps transfer rates.

But it would have been cool though
Any suggestions of what to do?
As I said, I have lousy samba performance as well.
I don't think my hdd:s are the bottlenecks either, any suggestions? |

Maybe you should raise tcp window sizes a bit higher? At least in a gigabit LAN that sure is an issue to look at. Try to increase values in the following locations:
/proc/sys/net/core/rmem_default
/proc/sys/net/core/wmem_default
/proc/sys/net/core/rmem_max
/proc/sys/net/core/wmem_max
/proc/sys/net/ipv4/tcp_rmem
/proc/sys/net/ipv4/tcp_wmem
On the other hand, if you are using ProFTPd as your ftp-daemon, make sure it's using bigger window than the default 8192 bytes. Add to proftpd.conf lines
| Code: | SocketOptions rcvbuf 262144
SocketOptions sndbuf 262144 |
