Step-by-Step Guide: Professional CDN Performance Analysis

Prerequisites

• CDN access and monitoring tools
• Understanding of streaming delivery fundamentals
• Network analysis and troubleshooting knowledge

Step 1: Basic Performance Testing

curl -w "@curl-format.txt" -o /dev/null -s "https://cdn.example.com/video/segment.ts"

Measure basic CDN performance metrics including response time, transfer speed, and connection characteristics.

Step 2: Streaming Manifest Analysis

curl -H "Range: bytes=0-1023" "https://cdn.example.com/video/playlist.m3u8" && time curl -s "https://cdn.example.com/video/playlist.m3u8" > /dev/null

Analyze manifest delivery performance and partial content support for streaming optimization.

Step 3: Geographic Performance Testing

for region in us-east us-west eu-central; do echo "Testing $region"; curl -w "Time: %{time_total}s, Speed: %{speed_download}" -o /dev/null -s "https://$region.cdn.example.com/video/test.mp4"; done

Test performance across different geographic regions to identify regional optimization opportunities.

Step 4: Bandwidth Scaling Analysis

for bitrate in 500k 1M 2M 4M; do echo "Testing $bitrate"; time curl -s "https://cdn.example.com/video/${bitrate}/segment.ts" > /dev/null; done

Analyze CDN performance across different bitrate levels to ensure consistent delivery scaling.

Advanced CDN Analysis Tools Techniques

Multi-CDN Performance Comparison

for cdn in cloudfront cloudflare fastly; do echo "Testing $cdn"; curl -w "CDN: $cdn, Time: %{time_total}s, Speed: %{speed_download}\n" -o /dev/null -s "https://$cdn.example.com/video/test.mp4"; done

Compare performance across multiple CDN providers to optimize routing and failover strategies.

Continuous Performance Monitoring

while true; do timestamp=$(date); response_time=$(curl -w "%{time_total}" -o /dev/null -s "https://cdn.example.com/video/segment.ts"); echo "$timestamp: $response_time"; sleep 60; done

Implement continuous monitoring to track performance trends and identify degradation patterns.

Real-World Use Cases

Use Case 1: Live Streaming Performance

Scenario: Monitor and optimize CDN performance for live streaming events Solution: Real-time performance monitoring with automated failover and optimization

curl -H "Cache-Control: no-cache" -w "Latency: %{time_total}s" -s "https://cdn.example.com/live/stream.m3u8"

Use Case 2: VOD Delivery Optimization

Scenario: Optimize CDN configuration for video-on-demand content delivery Solution: Analyze caching behavior and optimize for popular content delivery

curl -I "https://cdn.example.com/vod/popular_video.mp4" | grep -E "(Cache-Control|X-Cache|Age)"

Use Case 3: Global Performance Validation

Scenario: Validate consistent performance across global CDN edge locations Solution: Systematic performance testing across all edge locations and regions

for edge in $(dig +short cdn.example.com); do echo "Edge $edge"; curl -w "Time: %{time_total}s" --resolve "cdn.example.com:443:$edge" -o /dev/null -s "https://cdn.example.com/video/test.mp4"; done
