It's probably just that my cache is 350GiB and it takes a long, long time to fill that up. (As in, the unused % has been falling slowly for three years and it's only just got close to zero in the last few months.) (Some GCs have run, but I have no idea why, given that when they ran the unused % was about 40%.)
