    You want QoS (Quality-of-Service) with PRIQ. Check out the Advanced
    Routing HOWTO if you're a glutton for punishment, or the OpenBSD/PF/ALTQ
    FAQ if you really want it done with as little pain as possible. ;-)

    I use this at home to a) prioritize upstream ACKs to optimize downloads,
    b) prioritize outbound DNS requests, and c) prioritize interactive SSH
    sessions. Everything else brings up the rear. Here's the relevant
    section from my pf.conf:

    ### Queueing ###
    altq on $ext_if priq bandwidth 225Kb queue { std_out, ssh_out, dns_out,
    tcp_ack_out }
    queue std_out priq(red default)
    queue ssh_out priority 4 priq(red)
    queue dns_out priority 5 priq(red)
    queue tcp_ack_out priority 6 priq(red)
    altq on $int_if cbq bandwidth 2Mb queue { std_in, ssh_in, dns_in }
    queue std_in cbq(default)
    queue ssh_in priority 4
    queue dns_in priority 5

    Check out the following doc. Even if you choose to use Linux's QoS
    instead, this will explain it much better than anything else I've seen.
