Sysbench: MySQL基准测试工具

SysBench 是一款模块化、跨平台和多线程的（MySQL、PGSQL）基准测试工具，用于评估对在高负载条件下运行数据库的系统性能。

介绍

sysbench 是一款基于 LuaJIT 的可编写脚本的多线程基准测试工具。它最常用于数据库基准测试，但也可用于创建不涉及数据库服务器的任意复杂工作负载。

已支持的数据库驱动程序：

mysql: MySQL 驱动程序
pgsql: PostgreSQL 驱动程序

测试类型：

fileio: 文件 I/O 测试
cpu: CPU 性能测试
memory: 内存功能速度测试
threads: 线程子系统性能测试
mutex: Mutex 性能测试

Usage:
  sysbench [options]... [testname] [command]

Commands implemented by most tests: prepare run cleanup help

General options:
  --threads=N                     number of threads to use [1]
  --events=N                      limit for total number of events [0]
  --time=N                        limit for total execution time in seconds [10]
  --forced-shutdown=STRING        number of seconds to wait after the --time limit before forcing shutdown, or 'off' to disable [off]
  --thread-stack-size=SIZE        size of stack per thread [64K]
  --rate=N                        average transactions rate. 0 for unlimited rate [0]
  --report-interval=N             periodically report intermediate statistics with a specified interval in seconds. 0 disables intermediate reports [0]
  --report-checkpoints=[LIST,...] dump full statistics and reset all counters at specified points in time. The argument is a list of comma-separated values representing the amount of time in seconds elapsed from start of test when report checkpoint(s) must be performed. Report checkpoints are off by default. []
  --debug[=on|off]                print more debugging info [off]

  --rand-spec-res=N  percentage of 'special' values to use (for special distribution) [75]
  --rand-seed=N      seed for random number generator. When 0, the current time is used as a RNG seed. [0]
  --rand-pareto-h=N  parameter h for pareto distribution [0.2]

Log options:
  --verbosity=N verbosity level {5 - debug, 0 - only critical messages} [3]

  --percentile=N       percentile to calculate in latency statistics (1-100). Use the special value of 0 to disable percentile calculations [95]
  --histogram[=on|off] print latency histogram in report [off]
