1 Gigibit Ethernet - Slow?
I bought 2 Dlink DGE-530T 1000 Mbps (1 Gbps) Ethernet cards to replace my
10/100 Mbps. To test it, I installed on 2 WinXP computers and linked with a Cat 5 crossover cable. The icons on the system tray showed "Speed: 1 Gbps" on both computers Then, I tried to download some files form one computer to another using both Share drive and Webserver, the result was so disappointed... on average it's about 3 MB/sec which is about 24 Mbps -- 24% of 100 Mbps!!! My old 10/100 Mbps could do the same???!!!! I assume 1000 Mbps would give me at least 200 Mbps in trasfer speed! Am I correct? Did I do something wrong? Is there something I need to setup in Windows, registry or some settings in driver to get faster speed? please help. Thanks |

The bottleneck is probably one of your hard drives. Try transferring a large (e.g. 500 MB) unfragmented file. You might need faster drives, maybe a new RAID0 setup.

You are always limited by the slowest link in the chain. The 32-bit PCI bus bandwidth is limited to 127.2Mbps, so 200Mbps is unrealistic. At the moment, gigabit ethernet (GbE) only tends to show real improvements for network backbones with 64-bit PCI 2.1 bus speeds. PCI-Express motherboards with Serial-ATA RAID-0 configurations will improve GbE speeds for workstations over the coming year, but you still might not reach 200Mbps with that. |

Nope, PC bus limit is around 127 MegaBYTES = 1000 MegaBITS. In a PC the PCI bus is one of the bottlenecks, but nowhere near signifiant enough to prevent 200Mbps the OP expected. |

Cat 5 cable, less than 10 feet.. as I said in first message, I bought the cards just to test it to see if I want to invest in the 1 Gbps switch (switch is expensive) "Bubba" wrote in message .. .

That's a VERY good idea... I should try that.

Gb uses all 4 pairs of wires, http://logout.sh/computers/net/gigabit/ I don't know if such a cable problem would result or change the "1 Gbps" icon you see or not.. in a perfect world it would, but in this one??? |

GB ethernet will run over Cat. 5 cable no faster than 100 Mbps. GB ethernet
requires Cat. 6 cable. -- DaveW "Brandon Brown" wrote in message .cable.rogers.com... I bought 2 Dlink DGE-530T 1000 Mbps (1 Gbps) Ethernet cards to replace my 10/100 Mbps.
