i think i've got my network running at 100Mbps, instead of 10Mbos, but i'm not sure. How can i find how fast it is actualy running?

I got a windoze prog (anyspeed) which is saying i'm pining my gateway at 8000KBps. if i'm right, that makes 8megs per second, which is like.. 65Mpbs? that sounds about right cos it coiped a 650Mb avi file over in just over 1.5 minutes...

650megs/8megs per sec = 81 seconds... ?

is that all abuot right? i know i'm presumably not going to actually get 100mbps (or am i?) but does this mena i'm offically at 100mbps, accepting collisions and all that junk?

It does sound all right to me!

100 Mbps is definitely a max-value that you will never reach! Running at 8MBps is about what you will get out of a 100Mbps network.

The remaining bandwidth is taking up by stuff like collisions, Ethernet-frames, control packets, hardware (-> packet loss ...) all that.

If you actually wanted to have 100 Mbps you would have to turn off all error correction on your network, send all packets just once and hope that they will arrive without errors in the right order.

Does this satisfy you or were you aming somewhere completely different? I could think of a small script that would output the network speed on some network interface.

HTH, Steave.
