VPSBench

Simple, fast and accurate VPS benchmarking script.

VPSBench helps you quickly evaluate CPU, Disk, Network, and Virtualization performance with clean and easy-to-read output.

Unlike traditional scripts, VPSBench focuses on real-world performance with mixed IO workloads and clear output.

---

Quick Start

One-line run (recommended)

curl -fsSL https://vpsbench.com/vpsbench.sh | bash

⚠️ For security, you may review the script before running.

Features

CPU Benchmark

• Single-core and multi-core performance (sysbench)
• Short and consistent test duration

Disk Benchmark (fio)

• Mixed workload (randrw, 50/50)
• Block sizes: 4K / 64K / 512K / 1M

• Outputs:

  • Read IOPS
  • Write IOPS
  • Total IOPS (real-world performance indicator)

Network Benchmark

• Multiple global test nodes:

  • Cloudflare (CDN baseline)
  • Tokyo / Singapore (Asia)
  • Los Angeles / New York (US)
  • Frankfurt (EU)

• Measures real-world download throughput

System Information

• CPU model, cores, frequency
• Memory and disk usage
• AES-NI support

Virtualization Detection

• Virtualization type (KVM, Docker, etc.)
• Hardware support (VM-x / AMD-V)
• Nested virtualization detection
