So I've got a network set up as follows. I have a server running Gentoo (kernel 2.6.22) and a client box running Windows Vista. Box have gigabit NICs and are connected to a gigabit switch. The problem is that when sending a file to the server, the transfer is ~60MB/s, which is fine, but if I download a file from the server, it transfers at ~12MB/s, which is rather less fun. All these transfers are occurring via samba.
| Code: | ethtool eth1
Settings for eth1:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 1000Mb/s
Duplex: Full
Port: Twisted Pair
PHYAD: 0
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: pumbg
Wake-on: g
Current message level: 0x00000033 (51)
Link detected: yes |
| Code: | mii-diag eth1
Basic registers of MII PHY #32: 1000 796d 001c c910 0de1 cde1 000d 2001.
The autonegotiated capability is 01e0.
The autonegotiated media type is 100baseTx-FD.
Basic mode control register 0x1000: Auto-negotiation enabled.
You have link beat, and everything is working OK.
Your link partner advertised cde1: Flow-control 100baseTx-FD 100baseTx 10baseT-FD 10baseT, w/ 802.3X flow control.
End of basic transceiver information. |
| Code: | lspci | grep Ethernet
00:05.0 Bridge: nVidia Corporation CK8S Ethernet Controller (rev a2)
02:08.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet (rev 10) |
The Nvidia NIC is onboard and isn't actually in use, the Realtek one is eth1 and is the offending NIC.
I'm not sure if posting my smb.conf will be of any help, but just in case

There's six shares all told, but they're all configured the same way.
The damnedest thing is that I had this working properly only about a week or so ago, but of course, I tend to fiddle about a fair bit and I must have somehow broken it. Normally I can fix anything I break with the help of the wiki and this forum's search function, but not this time. So how do I fix this? |
