so I compiled `bcachefs-testing` including 30792a137600d56957c2491a60879d5e95bbf1ef, but I'm afraid that doesn't make much of a difference: ``` iops-test-job: (groupid=0, jobs=40): err= 0: pid=867: Thu Feb 1 08:26:41 2024 read: IOPS=14.6k,...

random: ``` fio --filename=randomrw --size=1GB --direct=1 --rw=randrw --bs=4k --ioengine=libaio --iodepth=256 --runtime=120 --numjobs=40 --time_based --group_reporting --name=iops-test-job --eta-newline=1

FYI I just recompiled `bcachefs-v6.5` to make sure I can reproduce the older, faster numbers and get ``` iops-test-job: (groupid=0, jobs=40): err= 0: pid=856: Mon Feb 5 12:46:59 2024 read:...

also: it seems the version of `bcachefs-utils` plays a role. I'm currently on kernel build `bcachefs-v6.5` and first created my file system using `bcache-utils` from some time in August 2023...
