Try the command in https://www.reddit.com/r/emacs/comments/74hetz/emacs_everywhere/dnzj01v/ https://www.reddit.com/r/emacs/comments/74hetz/emacs_everywh... in your regular terminal vs eshell – piping is really slow in eshell. I guess it somehow reimplements `|` in elisp, possibly losing parallelism along the way. When I reran that command now in eshell, it took 13.4 seconds, during which time Emacs had 100% cpu all the time, and sort/uniq had almost nothing.
