As a specific benchmark, no. But that wasn't the point of linking to the PR. Although the command looks like a basic editor, it is surprisingly featureful.
Fuzzy search, regular expression find & replace.
I wonder how much work is going to continue going into the new command? Will it get syntax highlighting (someone has already forked it and added Python syntax highlighting: https://github.com/gurneesh9/scriptly) and language server support? :)
Right, these are more useful features, IMO, than the ability to rip through 125GB of data every second. I can live without that, but syntax highlighting's a critical feature, and for some languages LSP support is a really big nice-to-have. I think both of those are, in this day and age, really legitimate first-class/built-in features. So are fuzzy searching and PCRE find&replace.
Add on a well-built plugin API, and this will be nominally competitive with the likes of vim and emacs.
