That was back in december, when I had also ripped out the invsqrt
cache entirely with things like "bcake".

(I still do not see any point to the invsqrt cache, nor )

I did some informal testing of recent cakes about a month back.. and
went back to fq_codel. cake ate too much cpu, queue depth was longer,
throughput at 50ms or longer, worse.

I decided that I'd much rather work on wifi.

Please test at longer rtts.
