If you are talking about using ip over FireWire, the performance of
this is nowhere close to the speed of disk transfer. In tests I
recently did on my machine, ip over firewire was slower than 100Mbit
ethernet for both FW400 and FW800 connections (copying 100Mbyte files).
This is consistent with what I've been told by Apple personnel - ip
over firewire is intended as a convenience for connecting two machines
and not a high-performance interconnect.
Keep in mind my testing was just to look at ip over FW as an
alternative to a 100Mbit ethernet connection, and I'm not sure that
this is the same context you are considering. However I thought this
was worth mentioning as I was initially surprised that ip over fw was
not actually that fast. If this is what you were considering, then
Gbit Ethernet would certainly be the way to go.
Hope this helps,
Rick

Hi,
If I could invest into a Workgroup Cluster from Apple, my first
dilemma would be what interconnection to use. Should I connect all
the nodes to a Gbit Ethernet switch using the 2 built in Gbit
interface or use the the two 800 Mbit/s Firewire connection to daisy
chain them or to connect them to a Firewire Hub ? The cluster would
have minimum 12 nodes and do mostly bio-informatics related number
crunching and statistical computation.
Is there any test "out there" which details the pros and cons of both
connection type?
Thanks ahead,
Janos

So, while openness provides a couple of security advantages in itself,
the chief reason why Linux and BSD offer superior security is not so
much because they're open source, but because they're not Windows. http://www.theregister.co.uk/content/55/36029.html
