MySQL Performance Test

The maximum connection number and IOPS are different according to different specifications of JCS for MySQL, see here.

Tutorial of performance test for JCS for MySQL is shown as below

Test Environment

  • All tests are completed in Availability Zone A of cn-north-1
  • Virtual Machines Specification for Test: 4C 16GB
  • Virtual Machines Image for Test: CentOS 6.5 64-bit
  • JCS for MySQL version for Test: 5.7

Test Tool


SysBench is a scriptable multi-thread benchmark test tool based on LuaJIT. It is mostly used for database benchmark test, but it can also be used to create any complex workload involving no database server.


  1. Download Link of sysbench, Click to Download
  2. Installation Commands
$ yum install gcc gcc-c++ autoconf automake make libtool bzr mysql-devel
$ unzip 1.0.zip
$ cd sysbench-1.0
$ ./autogen.sh
$ ./configure --prefix=/usr
$ make
$ make install

Database Instance Initialization

Create Account

See Create Account.

Create Database

See Create Database. You need to create a database named sbtest and remember to grant the read-write permission of new database to the account created previously when creating the database.

Test Commands

Data Preparation

$ sysbench ./share/sysbench/oltp_read_write.lua --table_size=10000000 --db-driver=mysql --tables=10 --mysql-host=XXX --mysql-user=XXX --mysql-password=XXX prepare

Pressure Test for Performance

$ sysbench ./share/sysbench/oltp_read_write.lua --tables=10 --threads=32 --max-requests=999999999 --time=3600 --table_size=10000000  --db-driver=mysql --mysql-host=XXX --mysql-user=XXX --mysql-password=XXX run

Environment Clear

$ sysbench ./share/sysbench/oltp_read_write.lua --tables=10 --threads=32 --max-requests=999999999 --time=3600 --table_size=10000000  --db-driver=mysql --mysql-host=XXX --mysql-user=XXX --mysql-password=XXX cleanup

Test Model

Table Structure

CREATE TABLE `sbtest7` (
  `k` int(11) NOT NULL DEFAULT '0',
  `c` char(120) NOT NULL DEFAULT '',
  `pad` char(60) NOT NULL DEFAULT '',
  PRIMARY KEY (`id`),
  KEY `k_7` (`k`)

Data Format

id: 1
  k: 5003504
  c: 98210233655-92920312724-46680254539-74097273196-30247159819-37778834059-40387910259-28547466616-68642657061-93956851311
pad: 13866500364-00628646396-45402716318-87575412098-94787248459

SQL Pattern


$ SELECT c FROM sbtest3 WHERE id=5007521
$ SELECT c FROM sbtest7 WHERE id BETWEEN 5000580 AND 5000679
$ SELECT SUM(k) FROM sbtest2 WHERE id BETWEEN 4992664 AND 4992763
$ SELECT DISTINCT c FROM sbtest6 WHERE id BETWEEN 5041654 AND 5041753 ORDER BY c


$ UPDATE sbtest2 SET k=k+1 WHERE id=4979352
$ DELETE FROM sbtest6 WHERE id=5037406
$ INSERT INTO sbtest4 (id, k, c, pad) VALUES (4995019, 4995155, '58990155292-53936825106-56125467619-3...

Test Indicators

  • TPS: Transaction Per Second, number of transactions performed by database per second, which is subject to commit.
  • QPS: Query Per Second, number of SQL performed by database per second (including insert, select, update, and delete.)
  • QT: Query Time, time for performing each request by database.
