I have a demo Spin application running on a small VPS [1] and the performance is amazing. It boggles the mind that the server is loading the WASM, instantiating a runtime, parsing markdown, applying templates, etc. all in just a few milliseconds. You can see the source for the blog [2], and the original blog engine Bartholomew [3] that it's based on.

Note this is a toy deployment, not actual content. Don't expect all the links to work or any content to be accurate or relevant :)
