I recently updated my FC5 from an old A7S333 board to and A8V board This board now has a 10/100/1000 NIC card on the MB. I have noticed however after upgrading my switch to a 10/1000 D-link, I can not achieve 1000Mbit speeds on my network. I do not see any problems in the log files or network configs. The D-Link indicates that both machines are currently 10/1000 connected. After testing speed by transferring a 6.3GB file between both machines, I get following results: 9min to transfer 6.3GB 700MB a minute 11.66 MB a second 93.333 Mbit/second ( not anywhere close to 1000 Mbit a sec ) All of this is going through Samba. If this makes any difference. I have 2 boxes on this network which are: 1: Intel 2.8GHz 800FSB (Asus P4P800-SE) w/ 10/100/1000 nic on MB (Win XP) 2GB Ram DDR400 2: AMD 3500 Athlon (Asus A8V) w/ 10/100/1000 nic on MB ( Fedora 5 32-bit ) 1GB Ram DDR400 Can anyone shed any light on the problem?
You will never obtain 1Gb/s, as that is the theoretical maximum. Assuming that everything else in your network is running at 1Gb/s, and there are no bottlenecks elsewhere, you should see at least 750Mb/s. I guess the first question is what makes you certain that the problem isn't on the Windows box? Beyond that, I'd like to see the output from: ethtool -i eth0 ethtool eth0 ifconfig eth0 How did you perform the measurements that you posted? Are you sure that you're not hitting disk IO bottlenecks? Is the problem only present with SMB, or other protocols as well? -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ L.
