ab tool will be installed when we install webserver apache

• Syntax:

  ab [options] [http[s]://]hostname[:port]/path

• Basic options:
  • -n requests Number of requests to perform
  • -c concurrency Number of multiple requests to make

• run benchmark website shop.babies.vn with 100 requests and 4 concurrency multiple requests:

  ab -n 100 -c 4 http://shop.babies.vn/

Download:

wget http://downloads.mysql.com/source/sysbench-0.4.12.5.tar.gz

Install:

yum install libtool
cd sysbench
./autogen.sh
./configure
make & make install

• Syntax:

  sysbench [general-options]... --test=<test-name> [test-options]... command

• Basic Options:

run script below:

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

output:

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!
Done.

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.

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

   output:

   sysbench 0.4.12.5:  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

       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

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
