[Bug 451169] Re: Performance really dropped with 2.6.31-8-rt

[Eric Schwandt]

Just base on output for about 5-10 minutes of cyclictest

Without adding nohz=on at boot: All three lines had minimum of 4, avg of
11 and maximum about 700.

When adding nohz=on at boot: T0 had a min of 5, avg of 33 and max about
700. T1 had a min of 5, avg of 25 and max about 700. T2 had a min of 5,
avg of 17 and max of about 700.

If I'm interpreting this right, it does seem that realtime performance
is better without the nohz=on being used.

But when it comes to playback of a medium sized project in Reaper
running under wine, performance is much better with nohz=on or with the
two previous rt-kernels. Maybe it is wine or wineasio that aren't
playing nice with the dynamic ticks being off.
