15 I don't run pf-sources, but I run a BFS-patched gentoo-sources. One of
16 the reasons I use it is because of its support for the SCHED_ISO process
17 priority, which is important for audio applications. Otherwise, I would
18 need to use a realtime-linux kernel, which is total overkill and I don't
19 want to reboot into a different kernel just for an audio session. Also,
20 SCHED_ISO works for normal users so I don't have to launch stuff like
21 jack-audio as root.
23 Another reason I use it is because my system becomes a bit more
24 responsive with BFS (meaning the GUI - I use KDE). You can do that with
25 the mainline scheduler too, but it's not automatic; you have to set up
26 the cgroups feature (creating different cgroups for different
27 applications), and I never bothered. It's up to the distro to provide a
28 cgroups setup, but I don't know whether Gentoo or any other distro
29 actually does it. My guess is not. Without a setup, users have to
30 launch their applications from the terminal, which is kind of stupid.
31 Launching them from the GUI will place them all in the same cgroup.
33 So BFS it is for me :-)
