sysbench 数据库性能测试

sysbench 是一款开源的多 线程 性能测试 工具，可以执行 CPU / 内存 / 线程 / IO / 数据库 等方面的性能测试。 数据库 目前支持 MySQL / Oracle /PostgreSQL。本文只是简单演示一下几种测试的用法，后续准备利用 sysbench 来对MySQL进行一系列的测试。具体的一些参数设置，需要根据不同的测试要求来进行调整


root@xuebinbin:~# sysbench --mysql-db=test --test=oltp --mysql-table-engine=innodb --oltp-table-size=1000000 --mysql-user=root --mysql-socket=/tmp/mysqld.sock prepare 
sysbench 0.4.12:  multi-threaded system evaluation benchmark

Creating table 'sbtest'...
Creating 1000000 records in table 'sbtest'...
root@xuebinbin:~# sysbench --mysql-db=test --test=oltp --mysql-table-engine=innodb --oltp-table-size=1000000 --mysql-user=root --mysql-socket=/tmp/mysqld.sock run 
sysbench 0.4.12:  multi-threaded system evaluation benchmark

No DB drivers specified, using mysql
Running the test with following options:
Number of threads: 1

Doing OLTP test.
Running mixed OLTP test
Using Special distribution (12 iterations,  1 pct of values are returned in 75 pct cases)
Using "BEGIN" for starting transactions
Using auto_inc on the id column
Maximum number of requests for OLTP test is limited to 10000
Threads started!
Done.

OLTP test statistics:
    queries performed:
        read:                            140000
        write:                           50000
        other:                           20000
        total:                           210000
    transactions:                        10000  (172.01 per sec.)
    deadlocks:                           0      (0.00 per sec.)
    read/write requests:                 190000 (3268.24 per sec.)
    other operations:                    20000  (344.02 per sec.)

Test execution summary:
    total time:                          58.1353s
    total number of events:              10000
    total time taken by event execution: 58.0398
    per-request statistics:
         min:                                  2.67ms
         avg:                                  5.80ms
         max:                                235.95ms
         approx.  95 percentile:               8.79ms

Threads fairness:
    events (avg/stddev):           10000.0000/0.00
    execution time (avg/stddev):   58.0398/0.00
