Performance Benchmarking

Overview

Skills in using stress testing and benchmarking tools.

sysbench

Installation

# Debian/Ubuntu
apt install sysbench

# CentOS/RHEL
yum install sysbench

CPU Testing

# 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

Memory Testing

# 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

Disk IO Testing

# 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 Testing

# 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 Disk Testing

Basic Testing

# 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

Configuration File

# 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 Stress Testing

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

Network Testing

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

Common Scenarios

Scenario 1: Server Benchmarking

#!/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

Scenario 2: Database Benchmarking

#!/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

Interpreting Results

Metric Description
TPS Transactions per second
QPS Queries per second
IOPS IO operations per second
Latency Response time
Throughput Data transfer rate

Troubleshooting

# 检查系统负载
uptime
vmstat 1

# 检查 IO
iostat -x 1

# 检查网络
sar -n DEV 1
