This seems ... large, no? # /usr/bin/time -f "RSS %M kb" ./fio --name=writetest --filename=/mnt/testfile1 --rw=write --bs=4096 --size=64M --iodepth=1 --ioengine=libaio --direct=1 --verify=sha512 --do_verify=0 RSS 1138748 kb and it got quite a bit larger with commit df8781b6 fio: groundwork for adding slat, lat percentiles i.e. if I check out the commit just before that, ab45cf07 Merge branch 'stat-averaging-interval-start-fix' of https://github.com/maciejsszmigiero/fio I get: RSS 782236 kb which is, if I'm reading it right, ~350mb smaller. 760mb seems pretty big for a simple fio job like this in the first place, that commit growing it by 350mb is unexpected and I ... haven't been able to figure out where that increase came from. Am I mis-analyzing something here? Thanks, -Eric
