I have been able to further correlate this. The issue is with incoming packet counters on either interface. When the flow reverses (upload speedtest vs download speedtest), the inside interface's ingress counter starts counting double instead. There is a single, seldom-used vlan, but it is only on the inside interface. Destroying it made no difference.

It may also be useful to try capturing packets on igb0 and correlating the number of captured packets with the counters.

Interface counter inaccurate
All, I've noticed that since upgrading to stable/13-n244514-18097ee2fb7c from 12.2-STABLE, throughput on my WAN interface (the box runs pf) is incorrectly showing double in systat -if, as well as in vnstat and pftop from ports. The LAN interface does not appear to be so afflicted. Running a speedtest on my 300Mb connection shows correctly in systat on a 12.2 client on the LAN, but on the router running 13-STABLE that it traverses, it shows ~600Mb. Someone suggested I send email here, as the pf counter code has recently been worked on. I'm happy to perform further testing, if desired.
