I also tested Marvell Yukon gigabit NIC instead of nForce4 with 40MB/sec on download from Linksys EG1032 and 23MB/sec uploading to Linksys EG1032. The same type of behavior with slightly different speeds (could be overall bad driver or lower end nic).
I have the latest driver for Linksys EG1032.
So, how come I cannot get 54MB/sec both ways? I turned off firewalls, virus scanners, servers too.
Now here comes the funny part. When I run the network bandwidth test in SiSoft Sandra 2007 I get good results: - Sandra test on nForce4 to EG1032: 56MB/sec speed, 96us latency - Sandra test on EG1032 to nForce4: 51MB/sec speed, 106us latency
Exactly what I would expect from these two computer setups.
I don't get it. Linksys EG1032 can supply 54MB/sec to nForce4 and the latter can download as much. But Linksys EG1032 cannot download at that speed, only half... I am sure that nForce4 can supply 54MB/sec though.
