    ：Test guidelines

    更新時間：Aug 24, 2023

    This topic provides guidelines for new users to test the performance of an ApsaraDB RDS for MySQL instance and submit a test report. After you submit a test report, you can receive additional discounts for instance renewal. If your test report is rated excellent, you are offered with substantial incentives from Alibaba Cloud.

    Prerequisites

    Background information

    ApsaraDB RDS for MySQL test activities.

    The following performance metrics are tested:

    • Transactions per second (TPS)

      The number of transactions that are executed by the RDS instance per second. A transaction is executed only after it is committed.

      • Use SysBench to test the performance of online transactional processing (OLTP) for executing a read/write transaction that consists of 18 read and write SQL statements.
      • Use SysBench to test the performance of OLTP for executing a read-only transaction that consists of 14 read SQL statements: 10 SQL statements are used to query data based on primary keys and 4 SQL statements are used to query data based on specified ranges.
      • Use SysBench to test the performance of OLTP for executing a write-only transaction that consists of four write SQL statements: two UPDATE statements, one DETELE statement, and one INSERT statement.
    • Queries per second (QPS)

      The number of SQL statements that are executed by the RDS instance per second. These SQL statements include INSERT, SELECT, UPDATE, DETELE, and COMMIT.

    SysBench parameters

    ParameterDescription
    db-driverThe database engine that the RDS instance runs.
    mysql-hostThe endpoint used to connect to the RDS instance.
    mysql-portThe port used to connect to the RDS instance.
    mysql-userThe username of the account used to manage the RDS instance.
    mysql-passwordThe password of the account used to manage the RDS instance.
    mysql-dbThe name of the RDS instance
    table_sizeThe size of tables used for the test.
    tablesThe number of tables used for the test.
    eventsThe number of requests sent for the test.
    timeThe time taken for the test.
    threadsThe number of threads invoked for the test.
    percentileThe percentage of execution durations that you want to analyze for the test to obtain an average execution duration. The default value is 95%. It allows you to obtain the average time that is required to execute a request for 95% of all the scenarios.
    report-intervalThe time interval at which you want to generate a test progress report. The value 0 specifies not to generate test progress reports but only to generate a final test report.
    skip-trxSpecifies whether to skip transactions. Valid values:
    • 1: specifies to skip transactions.
    • 0: specifies not to skip transactions.

    Test procedure

    1. Log on to your ECS instance and run the following commands to install SysBench:
      sudo yum install gcc gcc-c++ autoconf automake make libtool mysql-devel git mysql
git clone https://github.com/akopytov/sysbench.git
## Download the SysBench software package from GitHub.
cd sysbench
## Open the SysBench installation directory.
git checkout 1.0.18
## Switch to SysBench 1.0.18.
./autogen.sh
## Execute the autogen.sh script.
./configure --prefix=/usr --mandir=/usr/share/man
make
## Compile SysBench.
make install
    2. Test the performance of OLTP for executing read/write, read-only, and write-only transactions.
      • Test the performance of OLTP for executing read/write transactions.

        Run the following commands to perform the test (for more information, see SysBench parameters):

        ##Prepare the data used for the test.
sysbench --db-driver=mysql --mysql-host=XXX --mysql-port=XXX --mysql-user=XXX --mysql-password=XXX --mysql-db=sbtest --table_size=25000 --tables=100 --events=0 --time=300  --threads=XXX oltp_read_write prepare

##Run your workload.
sysbench --db-driver=mysql --mysql-host=XXX --mysql-port=XXX --mysql-user=XXX --mysql-password=XXX --mysql-db=sbtest --table_size=25000 --tables=100 --events=0 --time=300   --threads=XXX --percentile=95 --report-interval=1 oltp_read_write run

##Delete the data used for the test.
sysbench --db-driver=mysql --mysql-host=XXX --mysql-port=XXX --mysql-user=XXX --mysql-password=XXX --mysql-db=sbtest --table_size=25000 --tables=100 --events=0 --time=300   --threads=XXX --percentile=95  oltp_read_write cleanup

        Sample test results:

        • QPS: 23869.32
        • TPS: 1193.47
        • Response time (RT): 36.89 ms
        Test the performance of OLTP for executing read/write transactions
      • Test the performance of OLTP for executing read-only transactions.

        Run the following commands to perform the test (for more information, see SysBench parameters):

        ##Prepare the data used for the test.
sysbench --db-driver=mysql --mysql-host=XXX --mysql-port=XXX --mysql-user=XXX --mysql-password=XXX --mysql-db=sbtest --table_size=25000 --tables=100 --events=0 --time=300  --threads=XXX  oltp_read_only prepare

##Run your workload.
sysbench --db-driver=mysql --mysql-host=XXX --mysql-port=XXX --mysql-user=XXX --mysql-password=XXX --mysql-db=sbtest --table_size=25000 --tables=100 --events=0 --time=300  --threads=XXX --percentile=95 --skip-trx=1 --report-interval=1 oltp_read_only run

        • RT: 33.72 ms
        Test the performance of OLTP for executing read-only transactions
      • Test the performance of OLTP for executing write-only transactions.

        Run the following commands to perform the test (for more information, see SysBench parameters):

        ##Prepare the data used for the test.
