利用sysbench进行MySQL OLTP基准测试

 
Preface
 
    In order to know clearly about the real performance threshold of database server,we usually do database benchmarks.What's it?It's similar with preasure test of database in the whole system.The difference is that the database benchmark may not care about the real business performance but the direct performance with virtual data.It's simple and convenient to implement whereas what is more complex in presure test.The items what we really care about in database benchmark is TPS/QPS/RT(Response Time)/Concurrency,etc.I'm gonna use sysbench(one of the benchmark test tools) to do some basic oltp read write test of MySQL database today.
 
Introduce
 
    sysbench is a common tool used in database bentchmark to test MySQL database(of cource,it supports PostgreSQL and Oracle,too).It provide many test case through several built-in lua scripts by specifying option of "testname".We can use the tool to get performance statistics about CPU,IO,Memory,etc.

 summary
  • sysbench is more powerful than mysqlslap(built-in program of MySQL).
  • Be ware of  the diffrence between database benchmark test and presure test.
  • There're also some other tools can be used to test database performance such as mysql-tpcc,YCSB,etc.
  • Database benchmark really helps us to have a explicit overview about our newly arrived server.More test is necessary.
