Sounds like a sound justification to have this enabled to me.  Most
machines can enough memory to support this per-process overhead.

[Kernel-packages] [Bug 1655986] Re: lowlatency kernel is lacking support for latencytop

2017-03-07 Thread Mikko Rantalainen
I think that *-lowlatency-* kernels should include CONFIG_LATENCYTOP by
default. I agree that *-generic-* kernels do not need that. If
administrator has installed lowlatency kernel they clearly are
interested in lowest possible latency and Ubuntu should provide tools to
figure out where the current bottlenecks are.

Does popcon support querying for combination of lowlatency kernel AND
latencytop? Also note that since the CONFIG_LATENCYTOP was dropped,
latencytop is practically broken and cannot be used for anything, which
could explain its low usage.

(I also wonder if the increased RAM usage is *really* a big deal for
desktop class machines. Sure, CONFIG_LATENCYTOP may increase RAM usage
by 3848 bytes per task but for busy desktop or workstation running
around 1000 tasks that will result in increase of less than 4 *MB*. If
you're running 1000 tasks today, you probably have at least 4 *GB* of
RAM so the difference is less than 0.1%.)

[Kernel-packages] [Bug 1655986] Re: lowlatency kernel is lacking support for latencytop

2017-01-12 Thread Tim Gardner
We discussed this feature in July 2014 and decided then to disable it.
Unless there have been significant changes to the implementation I see
no reason to reverse our decision.
