Sabayon desktop kernels. Which scheduler used? [Solved]

[chris2kari]

New to Sabayon, about to try it. I read somewhere that Sabayon is one of a handful of distros that patch their desktop kernels with BFS.

What kernels is Sabayon using now in 9 series?
Vanilla?
Vanilla + BFS patch?

From Phoronix last year:

Fusion Kernel is a new effort led by the few Sabayon developers and it's aim is to be similar to the Zen Linux kernel sources. The Fusion kernel is supposed to be a "Sabayon-flavoured Linux kernel sources on steroids." Among its features are integration of the Brain Fuck Scheduler (BFS), the BFQ I/O scheduler, Reiser4 file-system support, experimental Btrfs patches, experimental DRM patches, and new wireless-next drivers.

and lead developer's blog last year:

Mitch and I, just started working on Fusion Sources. Like the glorious Zen Sources, ours are Sabayon-flavoured Linux kernel sources on steroids, containing Con Kolivas patchset (BFS included), BFQ io-scheduler, Reiser4, experimental btrfs patches, experimental drm patches, and experimental wireless-next drivers.

From the Lead developer's blog recently:

Before leaving for Dublin, we (as in the Sabayon team) are planning to release Sabayon 10. improved ZFS support, improved Entropy & Rigo experience (all the features users asked me about have been implemented!), out of the box KMS improvements, BFQ iosched as default scheduler (I am a big fan of Paolo Valente’s work) a load of new updates (from the Linux kernel to X.Org, from GNOME to KDE through MATE) and if we have time, more Gentoo-hardened features.

Thanks for your very comprehensive reply Fitz!
I really appreciate that you took so much time to answer my query in this way.
So in the current release vanilla kernels plus option to use fusion kernel, with next release using BFS default.
Thats good news to me. BFS cannot be objectively benchmarked AFAIK but, in use, I have found that desktop systems feel smoother & snappier with a little less CPU use observable.

I have a laptop set aside tor experimental testing/investigation of other more 'performance' oriented distro's. Sabayon/Gentoo makes the most sense to me after having tried _many_ others I really don't have the time/skills to do a from scratch Gentoo install at this point in time & like the feel of the Sabayon community.

Nice blog by the way Fitz!
Cheers!
