OK. I'm using an Intel NIC, according to lspci it is: Ethernet controller: Intel Corp. 82540EM Gigabit Ethernet Controller (rev 02) Using latest e1000 driver from Intel, from source. This host (fedora core 2) is on a gigabit segment on our LAN. Other (Mac OSX) hosts on this segment are not having the problem. An NT 4.0 box is on the 10/100 segment of the LAN. The fc2 host has smbmount-ed a directory on the NT machine. Here's the problem: file transfers between these two computers have become extremely slow. Talking 50k/s. Here's 'ifconfig -v eth0' output: eth0 Link encap:Ethernet HWaddr 00:07:E9:xx:xx:xx inet addr:192.xxx.x.xx Bcast:192.xxx.x.xxx Mask:255.255.255.0 inet6 addr: xxxx::xxx:xxxx:xxxx:xxxx/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:322464 errors:0 dropped:0 overruns:0 frame:0 TX packets:304204 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:327465261 (312.2 Mb) TX bytes:253277737 (241.5 Mb) Base address:0xd000 Memory:cff80000-cffa0000 Thought it might be samba, but scp file transfers are just as slow. And it's any host on the 10/100 segment, not just the NT box. I'm using the e1000 driver with the default parameter settings. Can anybody help?
