Hi Misc@,
Did anyone experience a high latency pings on em(4) interface post 5.0?
We have several machines on i386 -current with em(4) experiencing high
latency/RTT pings, and its really bothering our clients. Then we moved
the traffic/vlan to sk(4) interface and pings goes to the expected
behavior (compared to switch to switch ICMP pings). We applied altq bw
management for ICMP, and we tried to remove the bandwidth management
before switching to sk(4), but still no change on pings RTT.
