Complete Collection of VPS Testing Scripts: Latest 2026 Methods for VPS Performance and Network Speed Testing

When we purchase a new VPS, it is crucial to test its performance. Using professional VPS benchmark scripts, we can comprehensively understand the server's CPU performance, memory speed, disk I/O, network quality, and stability. If we encounter a machine with performance below expectations, we can promptly request a refund to avoid wasting money.

Complete Collection of VPS Testing Scripts

1. Fusion Monster Benchmark Script - GO Version

This is a comprehensive VPS performance benchmark script. The GO version, compared to the previous Shell version, has no environment dependencies, completely avoids referencing third-party shell files, and supports new features like testing in non-root environments.

2. YABS (Yet Another Benchmark Script)

YABS is a VPS performance benchmark script popular among users on foreign VPS forums. This script automatically runs top-tier industry benchmark tools, includes multiple tests to evaluate server performance in key areas: using fio for disk performance, iperf3 for network performance, and Geekbench for CPU/memory performance. It requires no installation of external dependencies and can run without elevated privileges.

Benchmark Script

curl -sL https://yabs.sh | bash

Or use

wget -qO- yabs.sh | bash

Open Source Address:https://github.com/masonr/yet-another-bench-script

3. Other Scripts

Below are some scripts that were once very popular but have slower updates now and fewer users. If the two commonly used VPS performance benchmark scripts above do not meet your needs, you can also choose from these scripts for testing.

How to Use Benchmark Scripts?

First, you need to connect to your VPS using an SSH tool. Naiba uses Xshell. Refer to:Tutorial on Connecting to VPS with Xshell 8_How to Log into VPS from Computer – Naibabiji

After connecting to the VPS, copy and paste any of the script commands above into the operation interface, press Enter, and you can start testing the VPS performance or network speed.

How to Interpret Benchmark Results?

Interpretation of Disk IO Test Results

• Excellent: > 200 MB/s
• Good: 100-200 MB/s
• Average: 50-100 MB/s
• Poor: < 50 MB/s

Network Speed Test Interpretation

• International Bandwidth: > 100 Mbps is excellent
• Domestic Speed: Judged based on line quality
• Latency: < 100ms is excellent, 100-200ms is good

UnixBench Score Interpretation

• < 500 points: Poor performance, suitable for lightweight applications
• 500-1000 points: Medium performance, suitable for personal websites
• 1000-2000 points: Good performance, suitable for small and medium-sized enterprises
• > 2000 points: Excellent performance, suitable for high-traffic websites

Choosing a VPS Based on Test Results

The UnixBench test result is a comprehensive score; here we primarily select VPS based on the test results from Fusion Monster/YABS.

Quick Decision Rules (30-Second Decision Method)

Rule 1: One-Vote Veto System

If any item fails, the overall rating is downgraded:

• ❌ Disk 4K Read < 5,000 IOPS → Not Recommended for Purchase
• ❌ Network Download < 100Mbps → Not Recommended for Purchase
• ❌ CPU Score < 600 points → Consider with Caution

Rule 2: Cost-Effectiveness Calculation Formula

性价比分数 = 4K随机读IOPS ÷ 月费美元

Judgment Criteria:

• < 1,000 points: Low Cost-Effectiveness ❌
• 1,000-2,000 points: Medium Cost-Effectiveness ⭐⭐
• 2,000-4,000 points: High Cost-Effectiveness ⭐⭐⭐

Test Result Summary:

• CPU Performance (sysbench): 607 points
• Memory Speed: Read 11.6GB/s, Write 10.0GB/s
• Disk 4K Random Read: 32,700 IOPS (32.7k)
• Network Download Speed: 6.7 Gbps (approx. 6,700 Mbps)
• Monthly Fee: $6 USD

Step 1: Check Key Metrics Against Qualification Threshold

Qualification Threshold Standards (2026):

1. Disk 4K Random Read: > 5,000 IOPS ✅
2. Network Download Speed: > 100 Mbps ✅
3. CPU Performance: > 600 points ✅
4. Memory Speed: > 5,000 MB/s ✅

Case Analysis:

• Disk: 32,700 IOPS ✅ (Far exceeds the 5,000 requirement)
• Network: 6,700 Mbps ✅ (Far exceeds the 100 Mbps requirement)
• CPU: 607 points ✅ (Just meets the standard)
• Memory: 11,600 MB/s ✅ (Far exceeds the requirement)

Conclusion: All key metrics are qualified. This is a qualified VPS!

Step 2: Calculate the Value-for-Money Score

Simple Formula: Value-for-Money Score = 4K Random Read IOPS ÷ Monthly Cost in USD

Value-for-Money Judgment Criteria:

• < 1,000 points: Low Cost-Effectiveness ❌
• 1,000-2,000 points: Medium Cost-Effectiveness ⭐⭐
• 2,000-4,000 points: High Cost-Effectiveness ⭐⭐⭐
• > 4,000 points: Extremely High Cost-Effectiveness ⭐⭐⭐⭐

Case Judgment: 5,450 points → Extremely High Value for Money ⭐⭐⭐⭐

Practical Application: How to Choose Your VPS

Scenario 1: Personal Use (Blog, Small Website)

Requirement: All metrics need to meet the baseline. The Vultr machine tested above: Fully meets and performance far exceeds requirements ✅

Scenario 2: Enterprise Application (E-commerce, API Service)

Requirement: Requires better CPU performance. The Vultr machine tested above: Excellent disk and network, CPU slightly weaker, but basically usable ⚠️

Scenario 3: High-Performance Demand (Database, Gaming)

Requirement: Requires top-tier CPU and RAM. The Vultr machine tested above: CPU is the bottleneck, not suitable ❌

Now, you can go and test the value for money of your own VPS. Note: No matter how high the value for money is, if the key metrics are not up to standard, the machine you buy will just collect dust.
