Vercel Labs compiled a TypeScript port of the TypeScript compiler into a native binary (github.com)
Each compiler stage was compared against tsgo on TypeScript's own test corpus of roughly 12,500 files, and the project reports matching results on the tested cases. No benchmark results are published, only a script to produce them.
A commenter who tested it against the Go build confirmed it is faster than the Go version, but warned the code targets the subset of TypeScript that scriptc supports, so the result may be tuned to the toolchain.
