I used the sysbench tool, more info at
sysbench –test=fileio –file-total-size=1G prepare
sysbench –test=fileio –file-total-size=1G –file-test-mode=rndrw –max-time=300 –max-requests=0 run
sysbench –test=fileio –file-total-size=1G cleanup
RESULT:
sysbench 0.4.12: multi-threaded system evaluation benchmark
Running the test with following options:
Number of threads: 1
Extra file open flags: 0
128 files, 8Mb each
1Gb total file size
Block size 16Kb
Number of random requests for random IO: 0
Read/Write ratio for combined random IO test: 1.50
Periodic FSYNC enabled, calling fsync() each 100 requests.
Calling fsync() at the end of test, Enabled.
