That’s not really a big issue. In major OS like the BSD, SMP implementation are not that old. If we can have a full OS running in single core mode, we can have an application being performant too. I’m currently running OpenBSD on 4 cores and it’s basically 99% idle.

Bad coding is just bad coding.

It's basically idle because it's not doing anything. If you are streaming in markdown and code and then doing syntax highlighting on this code in real time, then rendering it on the screen you are doing actual work.

It's also all cpu bound work. The majority of the stuff on your screen is being rendered by the gpu.

You are really, really not. Not at LLM inference speeds at least. Frontier models output maybe 200 bytes per second on the fast end. I guarantee you that idle BSD box is still processing more than 200 bytes of whatever at any point in time. Streaming 200 bytes of LLM output through syntax highlighting, markdown rendering, and diff formatting, will still leave the box basically idle if done correctly. Claude Code has not done it correctly.

		Processors today are very fast. If you are spiking it on rendering diffs, you’re doing it wrong. I can’t even stress it building openbsd’s kernel.
