    Hi

    I have Computers Networked with 100Mbs Nics and Cat5 cable. This is supposed
    to run at 100Mbs. Anyone know how I can actually check the speed that the
    computers can transfer files etc..and If the full bandwith is being
    utilised.

    Thanks

    That's only a max speed and not to usually be expected between 2PCs,
    normally it's not possible to get that fast.

    Between PCs/Switches/Servers it's possible to get that however it's
    (from data at work) it's mainly at night during backups.

    Depending on the OS which you didn't mention.


    For multi platform solutions,

    iperf, will let you send data for x seconds or xMB to see how long it
    takes. This is for short tests only as it can flood a link easily.
    http://dast.nlanr.net/Projects/Iperf/

    I use MRTG/Perl/SNMP on the other systems, Win / Linux / Solaris etc.
    MRTG http://people.ee.ethz.ch/~oetiker/webtools/mrtg/
    Perl http://www.activestate.com/

    You can also use SNMP (part of the OS) and something like GetIf on a
    Wintel box. If you select the correct counter via SNMP GetIf will graph
    it.

    Typically I see (at home) on 2 systems DVD writing , 2 way multi GB file
    transfer 32Mbits/sec on a 1Gb link.

    As a comparison 3 instances of binary newsgroup downloads can average
    about 2Mbps or if lucky , doing FTP, copying a 100MB web site among
    other things will flood a 3Mbps download link from ISP, adding binary
    downloads from another odd server or 2 helps a lot..

    >computers can transfer files etc..and If the full bandwith is being

    Usually due to the way OS works, disks, how many transfers , you won't
    get 100Mbps. Most traffic is very bursty and small so you won't get full
    use of the 100Mbps unless the transfer is sustained. And there are
    multiple connections.

    Both tests from a P4 1.8GHz, SATA disk.
    File an ISO 4608,708,608 btyes, on 1Gbps switch.

    Both these connected to same switch.
    To a 100Mbps connected P3 CPU speed?, ATA100 disk
    max 42Mbps 13m30s

    To a 1Gbps AMD K6-2/500 , SCSI disk, recently formatted and almost empty
    max 10Mbps before pressing cancel after 20m.
    The switch traffic LED's were off more often than on.

    Yes, you didn't type a URL because you fucked it up, you illiterate
    shitwit. Of course your second mangled sentence shows you don't even
    know what the **** a URL is.
