Performance

A snappy shell is very important to me. My config includes a benchmark function that runs fish 10 times and presents the timings.

The latest benchmark run shows that we load a new shell pretty fast.

$ # MacBook Air (M3, 2024)
$ set fprof (mktemp)
$ fish --profile-startup=$fprof -c exit
$ awk 'NR==1 || $3==">"{print}' $fprof | string replace $HOME '~'
$ rm $fprof

You can also profile fish's startup with the following command:

fish --profile-startup=$__fish_config_dir/fishprof.txt -c "exit"
