Subject: [Bloat] fq_codel on macosx
Date: Sat, 8 Sep 2018 17:12:50 +0200	[thread overview]
Message-ID: <521EB406-0F8B-4043-A6ED-4C38B0B2B9D8@gmx.de> (raw)

Hi Dave, 

Jason Woringen just told me that macosx seems to include fq_codel now as well as some involved priority queues that I can not make much sense of. It might simply have inherited this from its freebsd underpinnings...

en4 is 1Gbps ethernet
