RE: [OT] Network speed

["Dean Barrett" <dean@xxxxxxxxx>]

Cheers for that Harry

The lights on the switch indicate 100mbit connections

The machine in question is a celeron 500 (one of the UKHA Kiosk machines)
so
i assume the actual machines speed is not a problem.

Cables are quite short - 30mtrs and seem to be good.

I shall do more investigation on the machine itself.




Dean.

That is equivalent to about 8Mbps or so, so seems somehwat slow.

There are many reasons why you get poor speeds, and you don't give
enough info to guess.

1) Make sure that you are running full-duplex everywhere. A
good switch will tell you if you are.

2) Make sure that you are actualy running at 100Mbps - again a
good switch will tell you. Note that the speed you are getting is
equivalent to the switch only running at 10Mbps.

3) Many times the speeds are reduced because the OS on the PC
has a problem. If the files are fragmented, and the drives are slow
then this can reduce speeds, although to get down to these speeds
something major would be wrong. Unless one of the machines was old.
Poor network cards can sometimes cause this as well.

4) Are the cables good cables, and are they shorter than the
max length of 100m?

Harry.
