Hi all,
I'm testing bonding.c with two gigabit ethernet links toward a HP 2848
switch. My kernel is 2.4.24 from kernel.org on RedHat 9.0
modules.conf is like this :
[root at node01 root]# cat /etc/modules.conf
alias eth1 bcm5700
alias eth2 bcm5700
alias bond0 bonding
options bond0 miimon=100 mode=balance-alb updelay=50000
My problem :
I get a bandwidth around 900Mbit/s and not 1800Mbit/s with netperf or
iperf or NetPipe. Could you explain me why I'm not get 1800Mbit/s and
where is my problem ?
Thank you
Sincerely.
Jean-Marc
