GigaLAN ethernet speeds (1 Viewer)

[Nightmare77]

I know this doesn't relate to Media portal, but i was just wondering if someone who is running gigabit ethernet can share some of their transfer speeds, i have connected it up and used Qcheck and the results aren't to crash hot. See my results below, if someone can tell me what they get to see if this is normal or if its crap.
Connected at 100Mbps - 2.689Mpbs transfer speed
Connected at 1000Mbps - 275.862Mbps transfer speed.

Now i know that technically you divide the number by 8 so theoritically the max transfer speed should be 1000/8 = 125
But my understanding of that is that i should be able to transfer that equation which equals 125MB/sec

Does this sound correct?

If someone can post some other results that would be great.

Telecom equipment can reach up to 700Mbit/s on a Gigabit Ethernet port. Home equipment will probably reach less. Also consisder that you loose maybe 10% on application layer due to TCP/IP overhead.

One very common mistake is that the Ethernet ports use auto negotiation, which often failes. Try to set them to fixed "1000MBit, full duplex".

I i dont have a gigabit lan so i cant help you
but

If you wanted to change it from mega bits per second (Mbs) into mega bytes per second (MBs) yes thats correct.

The 100Mbps speed is terrible but the 1000Mbps is very much acceptable. Its being maxed out because the HDD is the bottleneck. Older PATA HDDs had transfer rates typically about 30-40MBps with the newer SATA pushing up to 60MBps. Raptors and raid will go even higher obviously.

yeah sorry i probably should have mentioned that its through a switch. Also the speed doesn't pick up at all with a shop bought cross over cable, so i'm starting to think its not a problem with my home cabling effort. Do you think the speed would be maxed out on a test program that just sends a 1meg file as a test to get these results ?

Getting the transfer speed will be most accurate with a better protocol like FTP. But which speed are you referring to? (You 1000mb speed is probably very close to maxed out if you using a single disk)

yeah i have been reading more and i think its more to do with the hdd speeds now, going from one new hdd to a pretty old 40gig on so that might be part of the slow downs
thanks guys
