三、使用 superspeed 测速（结果报错）
开源地址：https://github.com/i-abc/Speedtest
国内主要运营商（电信 / 联通 / 移动）速度
多个区域的 ping 值
这个文件已经找不到了：curl -fsSL https://bench.im/speedtest.sh | bash
curl -sL https://gitee.com/funet8/Rocky-Linux-Shell/raw/main/monitor/speedtest.sh| bash
源文件：
bash <(curl -sL https://raw.githubusercontent.com/i-abc/Speedtest/main/speedtest.sh)

经检测，speedtest-cli 的 SHA-256 与官方不符，方便的话欢迎到 GitHub 反馈 报错原因：https://github.com/i-abc/Speedtest/issues/19
四、网络质量测速 Speedtest
# 安装 speedtest-cli（Ubuntu/Debian）
sudo apt install -y speedtest-cli
# 安装 speedtest-cli（CentOS/RHEL）
sudo yum install -y speedtest-cli
# 运行测试

五. 使用 Geekbench
专业 CPU 跑分，一行命令
wget -qO- http://cdn.geekbench.com/Geekbench-6.2.2-Linux.tar.gz | tar xz --strip-components=1 && ./geekbench6测试结果
wget -qO- http://cdn.geekbench.com/Geekbench-6.2.2-Linux.tar.gz | tar xz --strip-components=1 && ./geekbench6
Geekbench 6.2.2 : https://www.geekbench.com/
Geekbench 6 requires an active internet connection and automatically uploads
benchmark results to the Geekbench Browser.
Upgrade to Geekbench 6 Pro to enable offline use and unlock other features:
https://store.primatelabs.com/v6
Enter your Geekbench 6 Pro license using the following command line:
./geekbench6 --unlock <email> <key>

六、查看内存占用工具 ps_mem
https://github.com/pixelb/ps_mem
使用
wget https://raw.githubusercontent.com/pixelb/ps_mem/master/ps_mem.py
python ps_mem.py
或者
wget -qO- https://raw.githubusercontent.com/pixelb/ps_mem/master/ps_mem.py | python3效果
root@developer:~# wget -qO- https://raw.githubusercontent.com/pixelb/ps_mem/master/ps_mem.py | python3
Private + Shared = RAM used Program
128.0 KiB + 15.5 KiB = 143.5 KiB fusermount3
96.0 KiB + 72.5 KiB = 168.5 KiB lightdm-greeter
100.0 KiB + 72.5 KiB = 172.5 KiB Xtigervnc-sessi
中间省略......
27.7 MiB + 5.8 MiB = 33.5 MiB Xorg
35.9 MiB + 0.5 KiB = 35.9 MiB snapd
13.6 MiB + 23.7 MiB = 37.2 MiB systemd-journald
28.3 MiB + 9.3 MiB = 37.6 MiB xfwm4
46.9 MiB + 8.0 MiB = 54.9 MiB xfdesktop
82.8 MiB + 9.6 MiB = 92.3 MiB Xtigervnc
---------------------------------
849.4 MiB
=================================
七、综合跑分 UnixBench
输出包含多项子测试及综合评分，数值越高性能越好。
# 安装依赖
sudo apt install -y build-essential perl
# 获取源码
git clone https://github.com/kdlucas/byte-unixbench.git
cd byte-unixbench/UnixBench
# 编译并运行
make
./Run
八、CPU 跑分：sysbench
关注 events per second（越高越好）和 total time（越短越好）。
# 安装
sudo apt install -y sysbench
# 测试 CPU（计算 20000 以内素数）sysbench cpu --cpu-max-prime=20000 run
九、磁盘 I/O：fio
关注 IOPS（每秒读写次数）和 BW（带宽）。
# 安装
sudo apt install -y fio
# 随机写测试
fio --name=randwrite --ioengine=libaio --rw=randwrite \
--bs=4k --size=1G --numjobs=4 --runtime=60 --group_reporting
十、网络带宽：iperf3
结果显示实际带宽（Mbps/Gbps）。
# 安装
sudo apt install -y iperf3
# 服务器端
iperf3 -s
# 客户端（替换 <server_ip>）iperf3 -c <server_ip>常用跑分工具分类
| 工具 / 脚本 | 测试范围 | 特点 | 适用场景 |
|---|---|---|---|
| UnixBench | CPU、内存、I/O、进程管理 | 经典综合基准，结果可横向对比 | 全面评估服务器整体性能 |
| Geekbench | CPU（单核 / 多核）、内存 | 跨平台，结果可上传对比 | CPU 性能对比、硬件评测 |
| sysbench | CPU、内存、磁盘 I/O | 可定制参数，适合压力测试 | 定向测试单一硬件性能 |
| fio | 磁盘 I/O | 支持多种 I/O 模式，结果详细 | 存储性能评估、数据库调优 |
| iperf3 | 网络带宽 | TCP/UDP 测试，支持双向 | 内网 / 公网带宽测试 |
| nench / bench.sh | CPU、磁盘、网络 | 一键脚本，快速出结果 | VPS/ 云主机快速评估 |
| glmark2 | GPU | 图形性能测试 | GPU 服务器评估 |
参考网站： 参考网站中有些地址失效，我下载到仓库中备用。
Linux 跑分测试工具种类丰富，从一键脚本到专业基准套件应有尽有。建议先用 bench.sh / nench 快速摸底，再用 UnixBench / sysbench / fio / iperf3 做针对性深测，最后结合业务负载进行优化。
