    Gigabit Network

    I was doing some checking and it seems my gigabit ethernet has a max transfer speed of about 90Mb/s. I used net stat live to check and the average transfer speed was about 85Mb/s. So I changed the max packet size to 9000 cause my netgear switch supports jumbo packets that size, still same speed.

    Switch is a GS108. My pc's have onboard lan, maybe that could be the slowdown?

    What prompted the checking was yesterday when I tried to get nvidia teaming to work, which was a dumb idea, cause it don't work.

    Your hard drive is the most likely suspect. The network can only move data as fast as it can be read from a drive and written to the destination.

    Besides you are getting very close to the limits, so everything would seem to be working right anyway.

    85Mb/s is close to the limit for gigabit speed???

    What are you doing to measure? That's actually very good if you're doing a transfer involving the hard drives. Assuming you meant to type "85 MB/s"

    A few factors....
    Hard drive speeds..don't forget home grade hard drives such as IDE/SATA..and even single SCSI drives...can't get near sustained speeds past that. Most averaging in the 65 range.

    NICs...if your NIC is an older one on the PCI bus...gigabit has 125 max...but if its an old NIC on the PCI bus..it has to "share" that bus which is rated at 133..with other devices...and realistically there's only about 85 megs on a PCI bus available to share. So gigabit on a PCI bus can never stretch its legs. If it's a PCI Express based NIC...then there's no problem. "Onboard" doens't mean bad...onboard can still be PCI Express based..as most new ones are.

    Antivirus real time protection..sniffing the file(s) being transferred...big slowdown.

    SATA hard drives. The Seagate 7200.10's in each box. One board was a 780i nvidia the other 680i, both with dual gigabit onboard. I transfered a folder full of small and large files from one box to the other and monitored with net stat live.

    I typed correctly, 85Mb not MB!

    I thought I would bump this thread cause it has the info in it still.

    You know I messed with things and updated drivers and this is better now. But the fasted speeds I have seen are about 35MB/s. Is there something I am overlooking or is this the best I can expect from nvidia on board controllers and SATA hard drives?
