In a network I have 3 linux systems. 2 of those are suse systems and the 3rd one is a linux firewall/router (not suse). The suse systems are a 9.2 and a 9.3 system. The outgoing ip/ethernet transmission speed of the 9.3 suse system is only 1.0-2.0 MB/s as reported by scp. While for the incoming traffic it is 6.0MB/s. This 6.0MB/s speed is measured for the other systems (fw <-> 9.2) as well. I wonder what can be reason why the outgoing speed is so low.
The network connection has been switched to another network port, but the outgoing speed remains low.
Does anyone have an idea what can be the reason for the low outgoing speed? Can this be caused by a bad network card, a hanging network process (although the system is almost idle)?? IMHO, that is a meaningless test. I would suggest that you install something

like ttcp or netperf on the 3 systems and run some tests.
I did this several years ago shortly after I got a 10/100 PCMCIA card for my
laptop that was recommended by a friend. I found that the card was giving
me no better than 10Mb.
I returned the card and got a cardbus version that tested close to 100Mb.
These utilities will give you a good test on your LAN. Remember that scp is
bogged down by encryption and some protocol overhead.
