| I still have 10mbit
My network has a 10/100 router and a 10mbit switch, thus half of it is 10mbit.
I would be happy just to have the whole thing at 100mbit, 100 is enough, at least until faster hard drive come out.

That's all I want. Data transfer across the network that matches my HD rates. Really, that's all! |

Re: I still have 10mbit
the fastest speed i can get on my 100mb lan is 87% of the theoritical max. I have a 7200rpm 8mb cache WD and 3200+, i dont see how anyone hopes to get half the capacity on a gigabit lan. I read this forum prob. last night and it seems like false advertisment to me considering Linksys' product push towards home consumers is so evident in places like Fry's Electronics. The manufactuer should make it clear what is needed to get those speeds on the box. |

I've managed to get a sustained 12.5MB/sec from my server to my computer using FTP, and about 9MB/sec using SMB by dragging and letting Windows copy..
FTP = FAST
SMB = Pretty fast |

| FireWire ok, Gigabit - Overkill
It seems to me that I've only transfered back and forth to my two computers of nearly identical hardware (Maxtor 80GB 7200rpm ATA-133 / SATA-150) a steady 30MB/sec read and write. I found this by using a FireWire (400Mbps) network. Seems to me like Gigabit for the home is a really big waste. I am going to be setting up a RAID and I will reply within a week if I get them in time the speeds which are read/writen over the FireWire. |

| Bottlenecks...
Well, lets see...
We have HDD access rates.
We have RAM cache.
We have CPU.
We have motherboard bus rates.
We have TCP adjustments.
We have driver software.
We have consumer hardware. (ie: cheap/affordable)
We have network settings.
Where's your bottleneck? |

|   report from Marion, Ohioh looking really well. got countless people online and MANY more to come. Everyday i have gone by the cable office there has been no where to park and the line has been insane. so i believe it will make adelphia a well know company in this area after powerlink is up and going.:) |

Re: I still have 10mbit
The whole point of Ethernet with it's small packet size (1500 bytes) is for a lot of traffic from many computers to flow at a good speed, not a few computers at a high data rate. It's more of a backbone technology, which is why in home networks, you never get full utilization. |

Kind of makes Giga-bit for the home seem like a huge waste of money then. |

Re: FireWire ok, Gigabit - Overkill
I have two Seagate 120 gig SATA-150 disks in a RAID 0 array. Guess what, you still cannot hardly touch gig. The biggest bottleneck with gig is the BUS speed of the machine. in fact, the most sure fire way to drive the CPU of a server up is to introduce gig-e. Gigabit, and 10 Gigabit ethernet has it's place. But the home most definitely is not it.

In reading book Martin Nemzow wrote titled Enterprise Network Performance Optimization. It refers to the fact that real world networks, with many factors that are involved in real use; the speed one can normally expect compared to the lab or ieee specification is 1/3 or 33 percent of performance rated. |

| Probably the biggest reason for that is poor network design. Usually there is something overlooked in the network layout, or in the architecture of one of the core switches that limits the throughput of the network as a whole. Careful planning will allow you to use most of your allocated bandwidth on the network.

Re: I still have 10mbit
Graph your traffic sometime. First of all, you have an internet connection that supports less than 5 megabits per second for the most part. That is more than likely the main source of your traffic. Just about the only other usage that is put on the average home network is files being copied from one system to the other. Gig is a waste at home.

Re: Nemzow says
 Hardly ever it is a network design issue my dear puritan. Business decisions and financial models usually temper the best non-blocking engineering designs. Oversubscription of links at the last mile or in the back bone is never the first choice of a good network engineer, but that of the MBA man running the financial spreadsheets... |

TCP/IP imposes a 10-15% overhead cost on any circuit.
If you are using a hub, you also have to deal with collision issues, in which case you hit the wall at 60% utilization. This is CDMA/CD after all, as in Collision Detection, not Collision Avoidance.
This is of course not factoring wiring crosstalk within cabling, interference from electrical and electronic devices (pumps, motors, anything at all, really), attenuation, improper termination, under-spec cable (you did get at least CAT 6/6e, didn't you?), and all the wondrous bottlenecks within the average PC.
In case you're bored, there are a legion software/firmware issues as well.
Unless you have a serious workstation with a server-grade motherboard, storage, CPU (can I have 2 please?), RAM, and a TOE (TCP/IP Offload Engine, a processor especially intended for handling TCP/IP traffic and taking that load away from the CPU), your drivers are well-written, and you don't have a crippled TCP/IP stack (like in Windows, any version), you will never see a near-1Gb effective throughput on your desk, let alone on the wire.
That sort of thing is doable in a properly configured switched copper gigabit backbone with Solaris 10 (yep, it's not out yet) or certain BSD/Linux-based systems, or with a FibreChannel storage array and storage switch using single-mode fiber pairs. It is also possible under laboratory conditions with a sizeable budget and good experimental controls.
Unless you fancy spending impressive cash for bragging rights, there is no practical application for this tech within the home. Switched 100Mb (megabit) over CAT 5/5e will give you approx 10MB/s (megabyte/second) throughput (best-case), which is sufficient for a high-quality video stream.
If you are running a business, please see above.

Re: Nemzow says
That was the biggest load I've read today.
Financial models have absolutely nothing to do with network designs.
If you implement a network that has a bottleneck, then it is a bad design. Which in turn makes it a design issue.
And not everyone has "good" network engineers.
