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.)
