How to Performance Test Your Server

Tools & Step-by-Step Guide

Hey everyone,

Performance testing your server doesn’t have to be complicated! Below is a guide that includes simple, downloadable tools and scripts (like bench.sh and Speedtest CLI) to help you benchmark your server’s performance quickly.

Quick-Use Tools for Server Testing

Here are some popular tools and scripts you can download and run in minutes:

1. Server Benchmark Scripts

bench.sh:
A lightweight script to test CPU, disk I/O, and network speed.
How to use:

curl -LsO bench.sh && chmod +x bench.sh && ./bench.sh

YABS (Yet Another Benchmark Script):

Tests CPU, disk, and network with a focus on geeky details.

curl -sL yabs.sh | bash

UnixBench:

A comprehensive benchmarking tool for Linux systems.

git clone https://github.com/kdlucas/byte-unixbench
cd byte-unixbench/UnixBench
./Run

2. Network Speed Tests

Speedtest CLI:

Official Ookla Speedtest tool for testing download/upload speeds.

# Install on Ubuntu/Debian:

curl -s https://packagecloud.io/install/repositories/ookla/speedtest-cli/script.deb.sh | sudo bash
sudo apt-get install speedtest

# Run:

speedtest

iPerf3:

Measure network bandwidth between two servers.

# Install:

sudo apt install iperf3 # Debian/Ubuntu
sudo yum install iperf3 # CentOS/RHEL

# Server mode:

iperf3 -s

# Client mode (test against server IP):

iperf3 -c [SERVER_IP]

3. Disk I/O & CPU Testing

dd Command:

Built-in Linux tool for basic disk speed testing.
# Test write speed:

dd if=/dev/zero of=./testfile bs=1G count=1 oflag=direct

# Test read speed:

dd if=./testfile of=/dev/null bs=1G count=1 iflag=direct

Stress-ng:

Stress-test CPU, memory, and disk.

sudo apt install stress-ng # Debian/Ubuntu
stress-ng --cpu 4 --io 2 --vm 1 --vm-bytes 1G --timeout 60s

Step-by-Step Testing Workflow

  1. Run a Quick Benchmark:
    Start with bench.sh or YABS to get a snapshot of CPU, disk, and network performance.
  2. Test Network Speed:
    Use speedtest or iperf3 to check bandwidth.
  3. Stress Test Resources:
    Use stress-ng or dd to identify hardware bottlenecks.
  4. Validate with Real-World Tools:
    Use JMeter or Locust to simulate user traffic.

Important Notes

  • Safety First: Only run scripts from trusted sources (e.g., GitHub repositories with good community ratings).
  • Compare Results: Use sites like OpenBenchmarking.org to compare your server’s performance against similar setups.
  • Automate: Schedule regular tests with cron jobs or CI/CD pipelines.
