# aio-stress [-s size] [-r size] [-a size] [-d num] [-b num]

# [-i num] [-t num] [-c num] [-C size] [-nxhlvOS ]

|
# file1 [file2 ...]
|
|
# -a size in KB at which to align buffers
|
|
# -b max number of iocbs to give io_submit at once
|
|
# -c number of io contexts per file
|
|
# -C offset between contexts, default 2MB
|
|
# -s size in MB of the test file(s), default 1024MB
|
|
# -r record size in KB used for each io, default 64KB
|
|
# -d number of pending aio requests for each file, default 64
|
|
# -i number of ios per file sent before switching
|
|
# to the next file, default 8
|
|
# -O Use O_DIRECT (not available in 2.4 kernels),
|
|
# -S Use O_SYNC for writes
|
|
# -o add an operation to the list: write=0, read=1,
|
|
# random write=2, random read=3.
|
|
# repeat -o to specify multiple ops: -o 0 -o 1 etc.
|
|
# -m shm use ipc shared memory for io buffers instead of malloc
|
|
# -m shmfs mmap a file in /dev/shm for io buffers
|
|
# -n no fsyncs between write stage and read stage
|
|
# -l print io_submit latencies after each stage
|
|
# -t number of threads to run
|
|
# -v verification of bytes written
|
|
# -x turn off thread stonewalling
