This page collects every measurement the Lab has published so far: five Hetzner Cloud servers in Helsinki (CX23, CX33, CX43 on x86 and CAX11, CAX21 on ARM), all rented and tested on 5 November 2026 with the same scripts, plus our production n8n server. Every table on the rest of the site is rendered from the same data file, so a number reads the same everywhere. The method is described in how we test.
