Subject: coreutils: sha256sum and md5sum very slow on ppc64el
Source: coreutils
Severity: normal
User: [email protected]
Usertag: ppc64el
Dear Maintainer,
The commands sha256sum and md5sum provided by coreutils are extremely
slow on ppc64el arch when run on somewhat large files.
Although when coreutils is configured and built with --with-openssl
flag, the performance gets significantly better.
So, the patch I am attaching does that. Could you please consider it?
Thanks!
