The first thing to try woul= d be to increase these to 4 or 8, depending on the number of cores in the system= .=20 Try this in loader.conf: hw.cxgbe.nofldtxq=3D"-8" hw.cxgbe.nofldrxq=3D"-8" Keep an eye on "netstat -dI -w1" when the system is under load. It= may be that there are packet drops leading to retransmits and loss of performan= ce. --=20 You are receiving this mail because: You are the assignee for the bug.=
