Can you > provide more details about how you were running these tests? it's just a normal fio run: fio --ioengine=rbd --bs=4k --name=foo --invalidate=0 --readwrite=randwrite --iodepth=32 --rbdname=fio_test2 --pool=teststor --runtime=90 --numjobs=32 --direct=1 --group Running one time with firefly libs and one time with dumpling libs.
