Benchmark with sysbench(CPU, File IO, MySQL)

Download and Install




yum install libtool
cd sysbench
make & make install

Syntax and Basic Options

  • Syntax:
    sysbench [general-options]... --test=<test-name> [test-options]... command
  • Basic Options:

CPU Benchmark

run script below:

sysbench --test=cpu --cpu-max-prime=20000 run


Running the test with following options:
Number of threads: 1
Random number generator seed is 0 and will be ignored

Doing CPU performance benchmark

Threads started!

Maximum prime number checked in CPU test: 20000

Test execution summary:
    total time:                          38.5596s
    total number of events:              10000
    total time taken by event execution: 38.5538
    per-request statistics:
         min:                                  3.69ms
         avg:                                  3.86ms
         max:                                 23.75ms
         approx.  95 percentile:               4.44ms

Threads fairness:
    events (avg/stddev):           10000.0000/0.00
    execution time (avg/stddev):   38.5538/0.00

And You see a lot of numbers, the most important of it is the total time:

total time:                          38.5596s

Of course, you must compare benchmarks across multiple systems to know what these numbers are worth.

File IO Benchmark

  1. Step1: Prepare:
    sysbench --test=fileio --file-total-size=5G prepare
  2. Step2: Run benchmark
    sysbench --test=fileio --file-total-size=5G --file-test-mode=rndrw --init-rng=on --max-time=300 --max-requests=0 run


    sysbench  multi-threaded system evaluation benchmark
    Running the test with following options:
    Number of threads: 1
    Initializing random number generator from timer.
    Random number generator seed is 0 and will be ignored
    Extra file open flags: 0
    128 files, 40Mb each
    5Gb 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.
    Using synchronous I/O mode
    Doing random r/w test
    Threads started!
    Time limit exceeded, exiting...
    Operations performed:  701100 Read, 467400 Write, 1495579 Other = 2664079 Total
    Read 10.698Gb  Written 7.132Gb  Total transferred 17.83Gb  (60.859Mb/sec)
     3894.99 Requests/sec executed
    Test execution summary:
        total time:                          300.0011s
        total number of events:              1168500
        total time taken by event execution: 134.9176
        per-request statistics:
             min:                                  0.00ms
             avg:                                  0.12ms
             max:                                 14.60ms
             approx.  95 percentile:               0.28ms
    Threads fairness:
        events (avg/stddev):           1168500.0000/0.00
        execution time (avg/stddev):   134.9176/0.00

    The important number is the Mb/sec value:

    Read 10.698Gb  Written 7.132Gb  Total transferred 17.83Gb  (60.859Mb/sec)
  3. Step3: Cleanup
    sysbench --test=fileio --file-total-size=5G cleanup

MySQL Server Benchmark

  1. Step1: To measure MySQL performance, we first create a test table in the database test with 1,000,000 rows of data:
    sysbench --test=oltp --oltp-table-size=1000000 --mysql-db=test --mysql-user=root --mysql-password=yourrootsqlpassword prepare
  2. Step2: Afterwards, you can run the MySQL benchmark as follows:
    sysbench --test=oltp --oltp-table-size=1000000 --mysql-db=test --mysql-user=root --mysql-password=yourrootsqlpassword --max-time=60 --oltp-read-only=on --max-requests=0 --num-threads=8 run
  3. Step3: To clean up the system afterwards (i.e., remove the test table), run:
    sysbench --test=oltp --mysql-db=test --mysql-user=root --mysql-password=yourrootsqlpassword cleanup

Benchmark with graphing software

Better Cacti Templates

Benchmark network speed

using speedtest

  1. Step1: install speedtest on linux:
    pip install speedtest-cli
  2. Step2: Run test

network monitor with iptraf


  • Install
    yum install iptraf
  • Run normal
  • Monitor Traffic on eth0:
    iptraf -s eth0

Benchmark File System Read Write Performance

Using dd command

  • Benchmarck the speed with which data was cached to RAM memory, not to the disk
    dd if=/dev/zero of=speetest bs=1M count=100


    100+0 records in
    100+0 records out
    104857600 bytes (105 MB) copied, 0.102163 s, 1.0 GB/s
  • Ask dd command to report the speed only after the data is synced with the disk
    dd if=/dev/zero of=speetest bs=1M count=100 conv=fdatasync


    100+0 records in
    100+0 records out
    104857600 bytes (105 MB) copied, 1.12073 s, 93.6 MB/s

Using hdparm

hdparm -tT /dev/sdb1


 Timing cached reads:   12982 MB in  2.00 seconds = 6500.84 MB/sec
 Timing buffered disk reads: 346 MB in  3.01 seconds = 115.04 MB/sec
