I have Samba server but to copy file of 500mb from one machine to another one it need 20minutes.

I use D-Link DI-707P router.

I set Linux server with ethtool to 100mbpsFullDuplex and also Windows system as well but now when I want to copy files my system frooze.

Questions:

Do theh both have to be set the same?
What Full&Half duplex mean?
What settings should I use to get maximum speed?

I use D-Link DFE-530TX+ and Marvell Yukon 88E8801/8003/8010 network adapters.

Thanks

Full-duplex
"Refers to the transmission of data in two directions simultaneously. For example, a telephone is a full-duplex device because both parties can talk at once. In contrast, a walkie-talkie is a half-duplex device because only one party can transmit at a time. Most modems have a switch that lets you choose between full-duplex and half-duplex modes. The choice depends on which communications program you are running"

The router should negotiate the speed and Full / half duplex settings with the computers NIC, and set accordingly.

Since you have a router (I assume that it has a built in switch), the two NICs do not (AFAIK) have to have the same settings. Also, most modern NICs will support 100Mbps, Full Duplex.

For maximum speed, use the fastest settings available.

Full duplex means the the link is bi-directional (Both parties can send and receive). Additionally, both parties can send and receive at the same time. This is similar to a telephone conversation.

Half Duplex is also a bi-directional link, however only one party can transmit at any one time. This is similar to a CB radio conversation.

AFAIK, Ethernet supports full duplex, while WiFi only supports half duplex. Use Full Duplex for maximum speed.

I think that the problem you have is likely to be to do with Samba, or some other settings.

I hope this helps
