From the initiator i connect to both the ports. TargetAddress = 192.168.253.253 Connected: da0 TargetAddress = 192.168.252.253 Connected: da1 I have setup the system to use gmultipath: gmultipath label -v TEST /dev/da0 /dev/da1 And then i've testing the performance, both with active/passive and actve/active. From what i have seen, the performance don't change that much, there is some stuff to configure that i'm missing?

I must miss some kernel dev knowledge :) Goal was then as a test to replace function calculate_crc32c() (I think thi= s is the one we are interested in) by the one provided in this header file. --=20 You are receiving this mail because: You are on the CC list for the bug.=
