Performance of bonding driver
|
|
Hi...
I have tw boxes which I linked together vi 2x gigabit interfaces and a
3Com switch. Each interface is:
02:0a.0 Ethernet controller: Intel Corporation 82541EI Gigabit Ethernet Controller
02:0b.0 Ethernet controller: Intel Corporation 82541EI Gigabit Ethernet Controller
The switch is private for them, so there is no more taffic.
One interface alone works pretty well:
[ 3] local 192.168.1.208 port 37739 connected with 192.168.1.226 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 1.00 GBytes 861 Mbits/sec
I loaded bondin driver with no parameters, and using iperf to test the connection
I get:
[ 5] local 192.168.1.208 port 5001 connected with 192.168.1.226 port 40036
[ ID] Interval Transfer Bandwidth
[ 5] 0.0-10.0 sec 812 MBytes 679 Mbits/sec
In the node which receives, two instances of iftop on slave interfaces
show that load is balanced, but none flies higher than about 300 Mb/s.
Any ideas ?
Is bonding dependent on CPU power ? Boxes are P4-HT [at] 2, 3Gb of RAM.
TIA
