bash: disable
bash-malloc
everywhere, not just on musl
TIme to time I bump into pathological behaviour of `bash` memory allocator. Today's example: $ time { ls /nix/store/ > /dev/null; } real 0m0,965s user 0m0,876s sys 0m0,087s $ time { echo /nix/store/* > /dev/null; } real 2m18,287s user 2m17,946s sys 0m0,125s $ time { echo /nix/store/* > /dev/null; } real 0m1,764s user 0m1,712s sys 0m0,048s Note how initial `echo` takes alsmot 2 minutes to finish. Let's rely on system's allocator instead. After the change initial run is fast again: $ time { echo /nix/store/* > /dev/null; } real 0m1,328s user 0m1,264s sys 0m0,063s
