The problem with this article is that the benchmark method they use is flawed. The documentation of zshbench explains why: https://github.com/romkatv/zsh-bench

Even with a low grade laptop, my zsh config grants me a sub 5ms prompt and a sub 1ms input lag, and that's far more important than the exit time.
