ast-grep is based on tree-sitter parsers and most of the time is spent on parsing.

There is some optimization to [skip parsing](https://github.com/ast-grep/ast-grep/blob/9f8ed5fb2abf35d928...) but generally I don't expect ast-grep can beat ripgrep or amber. (but sometimes ast-grep can beat grep due to parallel processing)
