I've stopp= ed my (extremely slow) copy to the drive and this background traffic continues. tty nvd0 da0 da1 cpu tin tout KB/t tps MB/s KB/t tps MB/s KB/t tps MB/s us ni sy in id 0 150 32.00 456 14.25 0.00 0 0.00 0.00 0 0.00 0 0 0 0 1= 00 0 493 32.00 455 14.22 0.00 0 0.00 0.00 0 0.00 0 0 0 0 1= 00 0 151 32.00 454 14.18 0.00 0 0.00 0.00 0 0.00 0 0 0 0 1= 00 0 164 32.00 455 14.21 0.00 0 0.00 0.00 0 0.00 0 0 0 0 1= 00 I've seen this on another system with Intel 750 PCIe cards but if I remember right it seemed to handle the background trim better. It's been a while sin= ce I tested it though. Both systems are test boxes so I can test any changes nee= ded and can move them to whatever base system versions are needed. --=20 You are receiving this mail because: You are the assignee for the bug.=
