fs-benchmark

This benchmark supports read-write and metadata performance test
on the wide distribute file system, such as ceph, moosefs, lizardfs and so on
and generates test graphs using pandas.

read-write test

This test uses iozone to run the read-write test
and includes write, read, randread, randwrite.

run and plot

cd /path/to/mount/fs
NAME=test TEST_LOOP=3 DIRECT="" bash $ROOT/rw-benchmark/iozone/perftest.sh | tee /tmp/testlog
# the result files is in $HOME dir
python $ROOT/rw-benchmark/plot/plot.py -f $HOME/iozone-test-<date>-{}.tar.gz -r 3

metadata test

metadata test tests the performance of MDS of ceph, or master of moosefs, or other fs

Usage of perftest:
  -b uint
        start index of operations
  -c uint
        concurrent of operations (default 1)
  -id uint
        client id (default 1)
  -interval duration
        interval to calculate tps, e.g. 1h5m8s (default 1m0s)
  -n string
        count string of operations, k,m,g (default "10")
  -period duration
        period duration of each stages, e.g. 1h5m8s (default 5m0s)
  -s string
        count of operations in one dir, k,m,g (default "10")
  -t    for test
  -v    show version
