[UniMacTech] Aggregated Network Ports

[Peter Thomas]

Dear All,

I have just installed a new gigabit Cisco switch to upgrade network  speed
in  my teaching labs and studios. The switch has some ports configured to
allow for aggregating or trunking ethernet cards on my servers and some of
my Mac Pro studio computers to provide faster transfer of large files and
faster image deployment. (Also maybe play with Final Cut distributed
rendering).

I have aggregated, (bonded) the two network ports on a Mac Pro tower and
done some rudimentary speed tests on this and another identical computer
that is configured to only use one network port.

My test basically was to copy the same 2 gig file across the network from
our server on both computers simultaneously and time them ­ expecting the
computer with the aggregated network ports to be twice as fast ­ not so
IDENTICAL    

I also copied the files back from the two machines back to the Server ­
again expecting the computer with the aggregated network ports to be twice
as fast ­ not so IDENTICAL

So how would I test whether I am achieving faster network throughput, on the
aggregated machine, is my test invalid or is something wrong with switch or
computer setup ?

Thanks
