The attached patch adds the (tunable? . #t) properties to additional
programs for which Clear Linux has an advantage over Ubuntu with the
same scheduler settings in a zen4 benchmark article

This is not guaranteed to help, but the article indicates possible
gains for these packages of 5-10%.

Best wishes,

Don't exceed the line limit even in a comment.
Properties are supposed to be the *last* field of a package.

Thank you — I moved the properties to the last field and moved the
explanation and description into the commit message.

A new patch is attached.

I’m reluctant to marking things like Chromium or OpenJDK as tunable
because they take ages to build: it’s more work for ci.guix (which
builds a few tuned variants of each tunable package), and possibly leads
to local recompilations for users when substitutes for their
micro-architecture are unavailable.

It’s also not immediately obvious to me why these two packages as well
as zlib would benefit from micro-architecture-specific optimizations.

Thoughts?

Ludo’.

What is the status of this patch?

Well, I also have mixed feelings about the tuning of these packages.

# Hi - looks like we didn't achieve consensus on this, due to concerns about CI. I guess one option would be to rework the patch for just the smaller packages and not Chromium/OpenJDK. Arne - if you'd like to do that feel free to re-open with a new version.
thanks
