Setting custom `process.title` in Node takes around 10-20ms. Vitest used to do this for every isolated test file so that debugging test runner processes was a bit nicer experience. But it's not worth the performance hit.

Vitest 4 runs simple test files faster! You can already check it out by installing Vitest 4 beta. On average, Vitest now takes 25% less time to start the test. Due to parallelisation, the overall time difference can vary. We are focusing our efforts on improving the time even more in the next beta!
