Innodb engine for database applications, users may be more concerned and oltp disk performance, and therefore the main test fileio oltp two projects
Test fileio
[Root @ iZ257l556beZ ~] # sysbench --test = fileio help

--file-block-size = N block size to use in all IO operations [16384]
--file-total-size = SIZE total size of files to create [2G]
--file-test-mode = STRING test mode {seqwr, seqrewr, seqrd, rndrd, rndwr, rndrw}
--file-io-mode = STRING file operations mode {sync, async, fastmmap, slowmmap} [sync]
--file-async-backlog = N number of asynchronous operatons to queue per thread [128]
--file-extra-flags = STRING additional flags to use on opening files {sync, dsync, direct} []
--file-fsync-freq = N do fsync () after this number of requests (0 - do not use fsync ()) [100]
--file-fsync-all = [on | off] do fsync () after each write operation [off]

--file-merged-requests = N merge at most this number of IO requests if possible (0 - do not merge) [0]
--file-rw-ratio = N reads / writes ratio for combined test [1.5]
Wherein the test mode into continuous / sequential write (seqwr), continuous rewrite (seqrewr), continuous reading (seqrd), random read (rndrd), random write (rndwr), random access (rndrw) six of them.
In man manual test sample, for example, requires a three-step test, such as:
$ Sysbench --num-threads = 16 --test = fileio --file-total-size = 3G --file-test-mode = rndrw prepare - prepare
$ Sysbench --num-threads = 16 --test = fileio --file-total-size = 3G --file-test-mode = rndrw run - test
$ Sysbench --num-threads = 16 --test = fileio --file-total-size = 3G --file-test-mode = rndrw cleanup - Clear test file
The first step in the implementation of test files generation
sysbench --num-threads = 16 - test = fileio --file-total-size = 3G - file-test-mode = rndrw prepare
Run the test for the second operation:
$ Sysbench --num-threads = 16 --test = fileio --file-total-size = 3G --file-test-mode = rndrw run
sysbench 0.4.12: multi-threaded system evaluation benchmark
