Hi all...
I'm trying to link an iBook and my linux box (kernel 2.6.9-rc4-mm1) via FireWire.
With static IP addresses, it seems to work, but performance is sloow (compared
to what I expected;):
werewolf:/usr/src/linux# iperf -c ibook
------------------------------------------------------------
Client connecting to ibook, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------
[ 3] local 192.168.0.1 port 33155 connected with 192.168.0.2 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 110 MBytes 91.8 Mbits/sec
werewolf:/usr/src/linux# iperf -c ibook-fw
------------------------------------------------------------
Client connecting to ibook-fw, TCP port 5001
TCP window size: 16.0 KByte (default)
------------------------------------------------------------
[ 3] local 192.168.1.1 port 33156 connected with 192.168.1.2 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 90.5 MBytes 75.8 Mbits/sec
Subnet 192.168.0 is an ethernet link (e1000 -> iBook), and 192.168.1
is the firewire one.
Hardware:
03:03.0 FireWire (IEEE 1394): Texas Instruments TSB43AB22/A IEEE-1394a-2000 Controller (PHY/Link)
Modules:
eth1394 18952 0
e1000 78516 0
ohci1394 29700 0
(iee1394 is compiled-in).
Where did I lost my 400Mb/s ?
TIA
(Please, people in the 1394 lists, CC me, I'm not subscribed. Thanks.)

Try transferring larger amounts of data. perhaps there is not enough
data to provide a meaningful bandwidth measurement.
HTH,
Michael
