Recently I established a share connection between an ubuntu 10.04 server and a windows 7 workstation.
The shared folder is on the win computer, and most traffic goes from server to workstation.
Both computers have Gbit nics and both have a lan connection to a Gbit router.
The speed of file transfers is disappointing, just 110Mbit. My internet connection has 120Mbit bandwidth and very often I reach 150Mbit.
I have tested my share connection with Iperf:
Code:
root@server:~# iperf -c 192.168.1.9 -w 2m
------------------------------------------------------------
Client connecting to 192.168.1.9, TCP port 5001
TCP window size: 256 KByte (WARNING: requested 2.00 MByte)
------------------------------------------------------------
[ 3] local 192.168.1.3 port 33442 connected with 192.168.1.9 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 1013 MBytes 850 Mbits/sec
root@server:~# iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[ 4] local 192.168.1.3 port 5001 connected with 192.168.1.9 port 55775
[ ID] Interval Transfer Bandwidth
[ 4] 0.0-10.0 sec 1.09 GBytes 933 Mbits/sec
In my humble opinion these test results look great, but question is what can be limiting my bandwidth.
The share connection uses samba cifs.
I am awfully inexperienced with network connections.
