esbuild is > 125x faster than Webpack, doing the exact same job. It's not some theoretical microbenchmark, you'll see it when converting a project from one to the other. If a software hasn't been designed with speed in mind, and I don't think tsc has, there can be massive performance improvements possible if you create a new implementation with performance as a top goal.

Webpack does way more than esbuild, including running a typechecking compiler instead of just transpiling, running compilers able to downlevel emit to ES5 and providing a deep plugin architecture allowing you to hook into any bit you like. But yes, it hasn't been designed with speed in mind - it has been designed for maximum extensibility instead. Its the same reason why Babel is slow compared to sucrase (written in JS, currently faster than SWC and esbuild but doing somewhat less - https://github.com/alangpierce/sucrase)
tsc has in fact been designed with speed in mind (I've been following the project since before it moved to GitHub, which is when they redesigned it for speed). Going beyond 1 order of magnitude performance improvement while implementing the full feature set is highly unlikely.

62X is still one order of magnitude.
I would bet on a port eventually being done and hitting at least 10X.
