Sysbench

Sysbench is a benchmarking tool that has several modes to bench:

• - fileio: This performs the file I/O test

• - cpu: This performs the CPU performance test

• - memory: This performs the memory functions speed test

• - threads: This performs the thread subsystem performance test

• - mutex: This performs the mutex performance test

• - oltp: This performs the OLTP test

To install it, run this command:

> aptitude install sysbench

The common test is to use the Online Transaction Processing (OLTP) scenario with small transactions to hit an optimized database. We will pass arguments to the command to simulate application threads (the --num-threads argument).

You can run this OLTP test with two kinds of scenarios:

• Read only (14 SELECT queries per transaction)

• Read/Write (14 SELECT, 1 INSERT, 1 UPDATE, and 1 DELETE queries per transaction)
