Checkout https://github.com/marknelissen/js-fullstack-benchmark/\n2. cd into either solidstart-solidrouter or solidstart-tanstackrouter\n3. `npm i \u0026\u0026 npm run build \u0026\u0026 npm start`\n4. other terminal on root of checkout\n5. `npm i \u0026\u0026 npm test`\n\n\n### Context 🔦\n\nI am working on a benchmark to quantify the overhead generated by several fullstack frameworks on server rendered pages. It's still a WIP, but the current results can be found, together with the tested implementations, on https://github.com/marknelissen/js-fullstack-benchmark/.\n\nI'm not certain if it is due some rate limiting protection build into solidstart, but if it is, I didn't find any documentation on it.\n\nIt seems unrelated to Solid itself, since Solid on tanstack start gives good results. Neither does it seem to reside in Solid Router, since with tanstack router, the same issue is observed.\n\nThe issue does go away by setting `ssr: false` in the config, meaning it is related to the server rendering.\n\n### Your environment 🌎\n\n```shell\nMacbook Pro M1 Pro 32GB RAM\n\nmacOS Tahoe 26.1\n\nNode 22.15.1\n```","author":{"url":"https://github.com/marknelissen","@type":"Person","name":"marknelissen"},"datePublished":"2025-11-14T15:07:44.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/2002/solid-start/issues/2002"}
