Before choosing a CDN, it is recommended to conduct actual tests:

# Global speed test tool
curl -o /dev/null -s -w "TCP: %{time_connect}s, TTFB: %{time_starttransfer}s, Total: %{time_total}s\n" https://your-cdn-domain.com/file

# Recommended testing tools
# 1. https://www.itdog.cn/ping/ - Multi-node Ping in China
# 2. https://tools.keycdn.com/performance - Global speed test
# 3. https://www.dotcom-tools.com/website-speed-test - Multi-location speed test
