I've set 40mpbs incoming and 9990kbps for outgoing on a 40000/9999 link as reported by the modem. Probably critically I've set the packet overheads to 12, and I now can't remember why... there's an on-wire vlan tag (4 bytes) but the reason for the other 8 have fallen out of the brain cell. I've a semi-regular backup job overnight that on a bad day overruns into the day - a week or so ago it ran for something like 2 days and I had absolutely no idea - thinkbroadband's ping monitor was registering something like an extra 5mS latency over the baseline, peaks were something like 25mS - backup stats and openwrt's stats package were registering the full 10mbps uplink in use during that time.
