One client has a large bandwidth ceiling. They're currently well

traffic to go through completely unimpeded. We're not dropping any
packets, but I'm seeing the "suspends" counter continually
incrementing, however, reaching tens of thousands in a matter of
queue dca bandwidth 64Mb
[ pkts: 40244 bytes: 22488217 dropped pkts: 0 bytes: 0 ]
[ qlength: 0/ 50 borrows: 0 suspends: 239 ]
What does "suspends" mean, actually? Is it anything to worry about?
in my experince, suspends happen when there's a need to borrow, but the
parent can't afford it. borrows happen increasingly as the queue get's
longer. drops happen when the queue overflows (n.b. red).
documentation in the altq field sucks, so don't treat this as absolute
truth. he who examineth the code shall see.
ps. your pf.conf would probably increase your chances of getting advice.
