I have a FreeBSD 10.2-RELEASE taking care of the bandwidth limitation of a small WISP. There are around 1400 dynamic queues and dynamic schedulers, and a big queue for a better QoS. Every scheduler and the big one for QoS have GRED configured. In this scenario, it's needed to compile my kernel with HZ=1000? And, in general, is it still needed to compile a custom kernel for dummynet to work more precisely? Thank you, Raimundo Santos
