I've got the following system: |

Linux server 2.6.26 #5 SMP Fri Feb 6 12:18:54 CST 2009 ppc64 PPC970FX, |

Setup on a cisco gig switch with both gigabit NICs in the following setup: |
| 7 |
|
| 8 |
% cat /proc/net/bonding/bond0 |
| 9 |
Ethernet Channel Bonding Driver: v3.2.5 (March 21, 2008) |
| 10 |
|
| 11 |
Bonding Mode: adaptive load balancing |
| 12 |
Primary Slave: None |
| 13 |
Currently Active Slave: eth0 |
| 14 |
MII Status: up |
| 15 |
MII Polling Interval (ms): 100 |
| 16 |
Up Delay (ms): 0 |
| 17 |
Down Delay (ms): 0 |
| 18 |
|
| 19 |
Slave Interface: eth0 |
| 20 |
MII Status: up |
| 21 |
Link Failure Count: 0 |
| 22 |

Both eth0 and eth1 are running at 1000Mb/s full according to ethtool. |

I start netserver (from netperf) on the server and then run netperf on |
| 31 |
four other singlegigabit connected clients on the same switch with: |
| 32 |
|
| 33 |
netperf -l 45 -t TCP_STREAM -H server |
| 34 |
|
| 35 |
but I get the following outputs: |
| 36 |
|
| 37 |

adding those up gives me: |
| 74 |
|
| 75 |
$ echo "405.68+216.07+143.93+164.05" | bc -l |
| 76 |
929.73 |
| 77 |
|
| 78 |
Not more than 1gbps. Shouldn't I be able to get >> 1gbps with balance-alb mode? |
