Hello list, while the performance of sequential writes 4k on bluestore is very high and even higher than filestore i was wondering what i can do to optimize random pattern as well.
While using: fio --rw=write --iodepth=32 --ioengine=libaio --bs=4k --numjobs=4 --filename=/tmp/test --size=10G --runtime=60 --group_reporting --name=test --direct=1 I get 36000 iop/s on bluestore while having 11500 on filestore. Using randwrite gives me 17000 on filestore and only 9500 on bluestore. This is on all flash / ssd running luminous 12.2.10.
