I guess I was hoping the WASM/IL trimming would be more aggressive. My comparison isn't very scientific, I'm mostly comparing things like https://fsbolero.io/TodoMVC/ which is done with Blazor vs https://yew-todomvc.netlify.com/ which is done with Yew. The former is nearly 6MB in total, the latter is 135KB.
Blazor client-side works by using the Mono runtime which is compiled and run as WASM. Your application is still delivered as standard DLLs and interpreted by that runtime.
They're working on making the runtime smaller and faster to start still a lag since your code has to be parsed and interpreted everytime, although the DLLs are pretty small already and easily compressed.
