Package: coreutils
Version: 8.26-3
Severity: normal
Dear Maintainer,
the sha{1,224,256,384,512}sum tools included in the coreutils package
can be compiled with libcrypto support. At the expense of a runtime dependency,
the speed gain of the hash calculation is quite noticeable under amd64:
matteo@saturno:~$ dd status=none if=/dev/zero bs=1G count=10 |time -p sha1sum
a0b6e2ca4e28360a929943e8eb966f703a69dc44 -
real 29.27
user 25.71
sys 1.68
matteo@saturno:~$ dd status=none if=/dev/zero bs=1G count=10 |time -p ./sha1sum
a0b6e2ca4e28360a929943e8eb966f703a69dc44 -
real 20.91
user 17.35
sys 1.67
while it's huge on aarch64:
matteo@macchiatobin:~$ dd status=none if=/dev/zero bs=1G count=10 |time -p
sha1sum
a0b6e2ca4e28360a929943e8eb966f703a69dc44 -
real 49.37
user 44.34
sys 3.11
matteo@macchiatobin:~$ dd status=none if=/dev/zero bs=1G count=10 |time -p
./sha1sum
