Benchmarking

Runs performance and load benchmarks using sysbench (CPU, memory, fileio and MySQL oltp tests), fio

by chaterm · Apache-2.0

The skill

Runs performance and load benchmarks using sysbench (CPU, memory, fileio and MySQL oltp tests), fio disk IO job files, HTTP load tools ab, wrk and hey, and iperf3 or netperf for network throughput and latency, then reads results such as TPS, QPS, IOPS and latency. Use when the user asks to benchmark a server, disk, database, HTTP endpoint or network, or to run stress tests with these tools.

性能基准测试

概述

压力测试、基准测试工具使用技能。

sysbench

安装

# Debian/Ubuntu
apt install sysbench

# CentOS/RHEL
yum install sysbench

CPU 测试

# 单线程
sysbench cpu run

# 多线程
sysbench cpu --threads=4 run

# 指定时间
sysbench cpu --threads=4 --time=60 run

内存测试

# 顺序读写
sysbench memory run

# 随机读写
sysbench memory --memory-access-mode=rnd run

# 指定大小
sysbench memory --memory-block-size=1M --memory-total-size=10G run

磁盘 IO 测试

# 准备测试文件
sysbench fileio --file-total-size=10G prepare

# 随机读写
sysbench fileio --file-total-size=10G --file-test-mode=rndrw run

# 顺序读
sysbench fileio --file-total-size=10G --file-test-mode=seqrd run

# 清理
sysbench fileio --file-total-size=10G cleanup

MySQL 测试

# 准备数据
sysbench oltp_read_write --mysql-host=localhost --mysql-user=root \
    --mysql-password=pass --mysql-db=test --tables=10 --table-size=100000 prepare

# 运行测试
sysbench oltp_read_write --mysql-host=localhost --mysql-user=root \
    --mysql-password=pass --mysql-db=test --tables=10 --table-size=100000 \
    --threads=16 --time=60 run

# 清理
sysbench oltp_read_write --mysql-host=localhost --mysql-user=root \
    --mysql-password=pass --mysql-db=test cleanup

fio 磁盘测试

基础测试

# 顺序读
fio --name=seqread --rw=read --bs=1M --size=1G --numjobs=1 --runtime=60

# 顺序写
fio --name=seqwrite --rw=write --bs=1M --size=1G --numjobs=1 --runtime=60

# 随机读
fio --name=randread --rw=randread --bs=4k --size=1G --numjobs=4 --runtime=60

# 随机写
fio --name=randwrite --rw=randwrite --bs=4k --size=1G --numjobs=4 --runtime=60

# 混合读写
fio --name=randrw --rw=randrw --bs=4k --size=1G --numjobs=4 --rwmixread=70 --runtime=60

配置文件

# test.fio
[global]
ioengine=libaio
direct=1
runtime=60
time_based

[seqread]
rw=read
bs=1M
size=1G

[randread]
rw=randread
bs=4k
size=1G
numjobs=4

fio test.fio

HTTP 压测

ab (Apache Bench)

# 基础测试
ab -n 1000 -c 100 http://localhost/

# 带 Keep-Alive
ab -n 1000 -c 100 -k http://localhost/

# POST 请求
ab -n 1000 -c 100 -p data.json -T application/json http://localhost/api

wrk

# 基础测试
wrk -t4 -c100 -d30s http://localhost/

# 带脚本
wrk -t4 -c100 -d30s -s post.lua http://localhost/api

hey

# 基础测试
hey -n 1000 -c 100 http://localhost/

# 指定时间
hey -z 30s -c 100 http://localhost/

# POST 请求
hey -n 1000 -c 100 -m POST -d '{"key":"value"}' http://localhost/api

网络测试

iperf3

# 服务端
iperf3 -s

# 客户端
iperf3 -c server_ip

# UDP 测试
iperf3 -c server_ip -u -b 1G

# 双向测试
iperf3 -c server_ip -d

# 多线程
iperf3 -c server_ip -P 4

netperf

# 服务端
netserver

# TCP 吞吐
netperf -H server_ip

# TCP 延迟
netperf -H server_ip -t TCP_RR

常见场景

场景 1：服务器基准测试

#!/bin/bash
echo "=== CPU 测试 ==="
sysbench cpu --threads=$(nproc) --time=30 run

echo "=== 内存测试 ==="
sysbench memory --threads=$(nproc) --time=30 run

echo "=== 磁盘测试 ==="
fio --name=test --rw=randrw --bs=4k --size=1G --runtime=30 --time_based

场景 2：数据库基准

#!/bin/bash
# MySQL OLTP 测试
sysbench oltp_read_write \
    --mysql-host=localhost \
    --mysql-user=root \
    --mysql-password=pass \
    --mysql-db=sbtest \
    --tables=10 \
    --table-size=100000 \
    --threads=16 \
    --time=300 \
    --report-interval=10 \
    run

结果解读

指标 说明
