Global Acceleration Test
Overview
Global Acceleration Test simulates real-world download scenarios by measuring the time it takes to download a 1 MB file from a selected origin location to multiple global destinations. It compares performance between the public internet and Zenlayer Global Accelerator (ZGA), allowing users to visually assess the acceleration benefit in terms of reduced latency and improved user experience. It usually has the following common use cases:
Common Use Cases
Cross-border experience testing
Evaluate download performance for users in different regions accessing a specific origin server
Acceleration effectiveness proof
Quantify the latency reduction achieved by Zenlayer Global Accelerator (ZGA)
Sales/PoC demonstration
Provide visual evidence of performance gains to prospects or customers
Network planning
Identify regions where acceleration is most needed or most impactful
Procedures
Parameter Explanation
Origin Location
The starting point of the file download, simulating the source server.
Download Time (ms)
The time it takes for a 1 MB file to be delivered from origin to destination. Lower is better.
Public Internet
Represents performance over the regular internet route.
ZGA
Represents performance when using Zenlayer Global Accelerator.
Acceleration (%)
The calculated improvement (reduction in latency) from ZGA compared to public internet.
Select one or more origin server locations, for example, Frankfurt, Ho Chi Minh City, Jakarta and Los Angeles.
Click Test, and the system will initiate download tests from the origin to multiple global destinations.
Each destination will show two latency measurements:
Public Internet: Download time without acceleration.
ZGA: Download time using Zenlayer Global Accelerator.
A percentage indicator shows how much acceleration improved download speed.
FAQ
Q1: What does the download time represent? A1: It reflects the time (in milliseconds) required to transfer a 1 MB file from the selected origin to each test destination.
Q2: Why are there large differences between regions? A2: Latency is affected by physical distance, network congestion, ISP quality, and routing paths. Regions farther from the origin typically see higher baseline latency.
Q3: Can this be used to estimate real-world performance? A3: Yes, it simulates real-world conditions, but results may vary depending on time of day, local traffic, and user network quality.
Q4: Is the test repeatable? A4: Yes, users can re-run the test at any time to observe latency under different conditions or compare results over time.
