Answer 1

In the Visual Studio Code settings you can configure the delay after which code analysis starts.

There is a delay because typically while writing such processing would be wasted effort and performance.

If you deem the delay too long, you can reduce it to your preferences.

Answer 2

This is working normally. Code highlighting and squiggles always take some time to load. They can take as little as ~0.5 seconds and as long as 5 seconds in a large project. Intellisense specifically waits for you to stop typing for a little while (about half a second maybe?) to even begin parsing the input and looking for errors.
