If it's an fio or iozone type command please post it here and I'll try the same thing. Are y= ou running cxgbei-offloaded iscsi on both the sides or is it only the initiato= r or target? I tried with 100G cards and cxgbei on both sides and didn't run into this problem. I'm going to try with 25G cards next. 2-3GBps would be close to = line rate for those cards and it may be that the performance falls off a cliff w= hen you get close to line rate and start seeing pause/drops. --=20 You are receiving this mail because: You are the assignee for the bug.=
