HTTP Global Speed Test Tool
HTTP Test HTTP/HTTPS Mode
Multi-node HTTP/HTTPS phased timing analysis with DNS/TCP/TLS/TTFB/Download breakdown, redirect tracking, response headers inspection, certificate details, and status code monitoring.
Online HTTP/HTTPS Global Speed Test Tool
This page performs multi-node HTTP/HTTPS speed tests, showing DNS, TCP, SSL, TTFB and download timing for each node. Ideal for evaluating global website access performance.
- Multi-node concurrent testing for quick comparison of access experience across regions.
- Phased waterfall chart to precisely locate DNS resolution, connection setup, TLS handshake and other bottlenecks.
- Grid and list layouts for easy multi-node horizontal comparison.
FAQ: What do the phased timings in HTTP speed test represent?
DNS is domain resolution time, TCP is connection setup, SSL is TLS handshake, TTFB is time to first byte, Download is content transfer time. Each phase helps pinpoint performance bottlenecks.
FAQ: What does high TTFB indicate?
High TTFB usually means slow server processing or backend response delay, possibly related to CDN origin pull, slow database queries, and more.
FAQ: Why do speed test results vary greatly across nodes?
Differences are usually caused by geographic distance, CDN coverage, carrier interconnection quality, and target server deployment location.
FAQ: What is the difference between HTTP and HTTPS speed test results?
HTTPS adds an SSL/TLS handshake phase compared to HTTP. If SSL time is too high, consider optimizing the certificate chain or enabling TLS 1.3.
