 This benchmark renders a table of 1000 rows with 10 columns (10k components), with around 30k normal elements on the page. Note this is not something likely to be seen in a typical app. This benchmark is mostly for stress/regression testing and comparing between `renderToString` and `renderToStream`.

 `renderToStream` pipes the content through a stream which provides considerable performance benefits (faster time-to-first-byte and non-event-loop-blocking) over `renderToString`. This can be observed through the benchmark.

 If you need to compile templates on the fly (e.g. passing a string to the `template` option, or mounting to an element using its in-DOM HTML as the template), you will need the compiler and thus the full build.

 Since the runtime-only builds are roughly 30% lighter-weight than their full-build counterparts, you should use it whenever you can. If you wish to use the full build instead, you need to configure an alias in your bundler.
