fxp0 is connected to broadband ISP _and_ local LAN which is going at
100Mbps - So I have 90Mbps queue defined for 'intranet' 876Kb for
'extranet' - Shouldn't the children of 'extranet' still 'borrow'
everything up to 876Kb? - Since I was defining root at 100Mb, I would
assume my queues would use up more, instead they are using _exactly_ what
is defined for them and refusing to borrow [hence going at 37KB instead of
the uplink max of ~100KB]. As soon as I 'up' the 34% to 60%, I get higher
dl speeds, although not using/borrowing above the 60%.
Changed the 100MB to 896Kb, and set the extranet to 886Kb, the rest for
intranet - Still no performance gain.
