in KB at which to align buffers 7 # -b max number of iocbs to give io_submit at once 8 # -c number of io contexts per file 9 # -C offset between contexts, default 2MB 10 # -s size in MB of the test file(s), default 1024MB 11 # -r record size in KB used for each io, default 64KB 12 # -d number of pending aio requests for each file, default 64 13 # -i number of ios per file sent before switching 14 # to the next file, default 8 15 # -O Use O_DIRECT (not available in 2.4 kernels), 16 # -S Use O_SYNC for writes 17 # -o add an operation to the list: write=0, read=1, 18 # random write=2, random read=3. 19 # repeat -o to specify multiple ops: -o 0 -o 1 etc. 20 # -m shm use ipc shared memory for io buffers instead of malloc 21 # -m shmfs mmap a file in /dev/shm for io buffers 22 # -n no fsyncs between write stage and read stage 23 # -l print io_submit latencies after each stage 24 # -t number of threads to run 25 # -v verification of bytes written 26 # -x turn off thread stonewalling 27 #
