(packets are going out bursty, with average hovering at ~500Mbps:ish) I recomplied kernel with IFQ_MAXLEN of 5000 but there seems to be no change in the behaviour. How do I make sure that em-interface is running 66/64 and is there a way to see interface queue depth? em0: <Intel(R) PRO/1000 Network Connection, Version - 1.3.14> port 0x3040-0x307f mem 0xfc220000-0xfc23ffff irq 17 at device 3.0 on pci2 em0: Speed:1000 Mbps Duplex:Full pcib2: <PCI to PCI bridge (vendor=8086 device=1460)> at device 29.0 on pci1 IOAPIC #2 intpin 0 -> irq 16 IOAPIC #2 intpin 6 -> irq 17 IOAPIC #2 intpin 7 -> irq 18 pci2: <PCI bus> on pcib2 The OS is 4.7-RELEASE.
