Multi-URL HTTP and HTTPS download throughput and latency benchmark
A multi-URL HTTP and HTTPS download speed benchmark, connection phase latency analyzer, and response header inspector for Linux. A lightweight Linux alternative to NirSoft DownTester for testing real download throughput across multiple web servers, mirrors, and CDN endpoints sequentially.
Key features:
- Measures exact connection phase timings per URL: DNS resolution (ms), TCP handshake (ms), TLS negotiation (ms) with cipher inspection, and Time-To-First-Byte (TTFB ms).
- Streams real HTTP and HTTPS payloads (Content-Length and chunked transfer encoding) with configurable byte-limit caps (256 KB, 1 MB, 5 MB, 25 MB, or full file) and computes live SHA-256 digests.
- Renders streaming MB/s and Mbps speed curves alongside a stacked DNS/TCP/TLS/TTFB latency comparison chart.
- Inspects complete HTTP status lines and response headers, and exports structured CSV and JSON benchmark reports.
