Ok, I got a bit further. I compiled in ALTQ and I am using Class Based
Queueing.
Here is a snippet of my pf.conf
altq on le1 cbq bandwidth 100Mb queue { std, cifs, http }
queue std bandwidth 88.5Mb cbq(default)
queue cifs bandwidth 1500Kb cbq
queue http bandwidth 1Mb cbq
Here is the problem, no matter what value I set for the CBQ Queue, its at
least 1/4 of the actual configured maximum. So I configured http for 1Mb,
the max throughput I get is 288Mb. Can anyone explain why?
