eth0 is doing all the work

eth1 does almost nothing

bond0 and br0 show the right amount of traffic but do not peak over 1 Gb/s

Are you sure that your moving enough data when you test the LACP? Say copying large 1-2G files to an SSD cache from 2+ clients at the same time.

absolutely,

 

I am accesing multiple disks from multiple clients, sadly no ssd but it  caps at around 980 Mbit/s

 

edit:

 

balance-rr works like a charm btw.. tested it with only two clients: 1,5 Gbit/s peak

DONE

 

bringing the interfaces down and up again via ifconfig does the trick

 

thread can be closed, thanks fo your help roberth58 !

 

best regards
