tsgo is about x4.3 faster than tsc when running in the design system package:

hyperfine "pnpm tsc" "pnpm tsgo"
Benchmark 1: pnpm tsc
  Time (mean ± σ):      4.233 s ±  0.094 s    [User: 6.848 s, System: 0.536 s]
  Range (min … max):    4.121 s …  4.406 s    10 runs
 
Benchmark 2: pnpm tsgo
  Time (mean ± σ):     986.7 ms ±  34.2 ms    [User: 3397.4 ms, System: 502.7 ms]
  Range (min … max):   951.3 ms … 1044.2 ms    10 runs
