Well for Blazor Webassembly at least, you need to download the entire .NET runtime and WebAssembly isn't quite as fast as JS in browsers yet.

Couple that with the fact that interoping with JS can be a lot more annoying than just using JS

It's a one-time download that's smaller than the initial load of the Facebook feed

What about the CPU usage?

Facebook loads a lot of information. I don't think we should be comparing the download size of a hello world app with loading dozens of images on a facebook feed.

Honestly I'm afraid you don't know what you're talking about. Blazor just isn't that experience and hasn't been for awhile.

Well color me convinced!

plus in LOB apps very likely to be in the browsers cache already. And dont forget buisness workstations are usually connected via at least 1GBit Ethernet.

I'm not who you're replying to but designing for excess resources is the kind of thinking that leads to slow software.

NOPE! More likely they are WiFi connected Dell shitboxes running Windows 11 with 8GB of memory, half of which is taken up by all the browser tabs, Teams, Office, and the 30 horrible little programs that IT deploys via group policy.

Speed matters. The user is probably running your code + 30 other things. Don't assume your page is the only thing they care about.

Any data to back this up?

Any data to back _your_ claims up? Because, y'know, sure, all _we_ have is years of lived experience.

If your point is that companies run outdated, shitty computers connected over unreliable WiFi, _your_ corporate life experience has been vastly different than mine.

That's not true since .net 6

.NET 8 is suppose to greatly improve AOT. Depending on your use case, you might be able to get around bundling the runtime entirely.

As far as I understand, .NET 8 AOT has nothing to do with the webassembly blob that gets served to the client.

They’re working on it. .NET 8 introduces the option to perform a degree of trimming on the AOT output. https://learn.microsoft.com/en-us/aspnet/core/blazor/host-an...

Actually dotnet wasm can be further trimmed in .net 8. but for most non rtl people the biggest improvement will be to reduce the locale bundle. Sadly it’s not possible to specify which ones you want. Also it’s not possible to bundle DLLs/webcil. I.e the dotnet compiler will be shipped to the client thus you will also get shipped lots of dlls

Blazor Hybrid looks promising to completely negate the load time for Blazor WASM.

Yes that does look promising for load time, but once the Webassembly is downloaded and being used, Non high end computers can easily choke.
