Poll: Anyone NOT experiencing >10% cpu in the menu on 0.22 ?

Sorry for the branch from my original thread: Mythfrontend idle cpu
consumption help. I thought I'd try to get the attention of those that may
have efficiently working machines...if they're out there.

There seems to be people in the original thread that seem to think the issue
I'm having IS happening to EVERYONE, and that this is by design. I see 14%
utilization from mythfrontend when it just sits idle on a menu screen while
the cpu is clocked at 1Ghz. With 0.21, I'm pretty sure it hovered between
0-2% utilization (what I'm calling normal).

So, as the Subject says, this a quick poll for those of you who have 0.22
installed. (I'm especially interested in those that are ubuntu based).

Who has a "normal" working 0.22 install and only sees 0-2% CPU utilization
when sitting idle on mythfrontend menu screens. If this describes the
behavior of your install, could you help me out in giving a short
description of your system.

mythtv 0.22-fixes
Mythfrontend utilizes between 2-3% of the cpu.
Centos 5.4
Intel(R) Pentium(R) 4 CPU 2.80GHz (HT disabled)
Running with the QT themepainter because OpenGL is not working for me
and I have not had a chance to troubleshoot it yet.

I have one of each. They netboot from the same image, so the software
shouldn't be significantly different. I'm on Ubuntu 9.10 Myth .22. The one
that is at 0% is an AMD X2 3800+ on an Asus M3N78 w/2GB RAM. 512MB is
dedicated to the onboard video with VDPAU. I believe it's also at the
MythVideo menu at the moment, while the other one using more CPU is at the
main Myth menu. No idea if that's significant. I never noticed the extra CPU
use at the menus. Not a big deal to me, though it is surprising. I wouldn't
have expected the CPU to be more than a few % busy sitting at a menu.

As sdkovacs mentioned, I think the machine using higher CPU is using the QT
painter. I'm quite sure the other one is using OpenGL. Could that be the
difference?

how are we measuring CPU?

MythBuntu 9.10 - Myth .22 from the aptitude.
AMD Phenom(tm) II X3 705e Processor
uptime shows load at 0.00 and top shows cpu at 3.2%

Right now my Athlon 2500+ is sitting at the main menu in blue abstract
using about 14% cpu.

Mythbuntu 9.10, Intel Atom 1.6GHz, NVIDIA Ion, using VDPAU and OpenGL painter with the mythbuntu theme. CPU usage for mythfrontend jumps around but averages about 6%. This is in line with my previous system, also Atom based but with Intel video, running 0.21, which used a similar amount of CPU. So I'd say mine's "normal".

I have occasionally had it where I select a video to play, and get a 'Please Wait' screen, followed by a frontend hang. Mythfrontend is using 25% CPU when that happens. Don't know if it's related to your issue but thought I'd mention it.

Mythtv 0.22-fixes

0.5%-1.0% CPU when idle on menu screen and nothing being recorded.

Fedora 10

AMD X2 Athlon 5200+

QT Painter with Graphite theme or Minimalist theme.

While recording from my HDPVR, mythbackend usually reports 2.5%-3% CPU, and
mythfrontend will report 6%-7% during playback, so unless there is a
mythcommflag job running, I don't hit 14% even while recording or watching
something.

Re: Poll: Anyone NOT experiencing >10% cpu in the menu on 0.22 ? [In reply to]

So, I'd say it is safe to say that the problem I and several others are
having with higher cpu usage while sitting idle on a menu does not affect
everyone. There has got to be something wrong other than alpha pulses
otherwise I would think it would affect everyone the same. I'm getting
tempted to try building mythfrontend for the first time just so I can reduce
the polling rate and rebuild as an experiment just to be done with this
issue!

No one seems to have a clue what it might be other than the 70Hz polling for
alpha pulse (which it sounds like is nothing new).

Tom,

Did you package the MythBuntu theme as an RPM for your Fedora machine? I've
seen this theme is fairly popular and was wondering if I was going to need
to download it from MythBuntu's website or if someone has it in RPM format
for Fedora hosts.

Thanks.

Its in the mythtv-themes 0.22 packages in RPM Fusion. Likely in the ATrpms packages as well, since its in the official themes tarball now.

It is in SVN, so I just use that. I compile everything for MythTV myself.

Re: Poll: Anyone NOT experiencing >10% cpu in the menu on 0.22 ? [In reply to]

I think the query about how you measure CPU usage is valid.

I'm running MythTV 0.22 under Ubuntu 9.10 on a Dell Latitude D810 (1.8Mhz
Cemtrino, 1.5Gb RAM)
It's got an external monitor as well as the builtin screen so I can monitor
he CPU using atop without disturbing the frontend.

Initially frontend.real used about 14% while backend used about 3%. After a
few minutes, the frontend usage dropped to 0% while the backend stays about
the same (maybe drops to 2% or even 1%). The only other non-zero process in
mysqld at 1% (sometimes). Apart from the odd spike in backend use (to 100% n
the hour) it's been like that for over 10 minutes now.

How are other people measuring the CPU usage?

FWIW,watching a DVB-T recording (720x480 onto laptop screen 1280x800) CPU
usage figures (from atop) are:

mythfrontend.real: 26%
Xorg: 5%
mythbackend: 3%
mysqld: 1%

The next process is atop itself (0%).

Side note: I don't know why I didn't see it before, but for the overall
system, I see top breaks down the cpu usage into several different
categories. My overall system call usage hovers around 10%.

On my main frontend box mythfrontend hovers around 2% using the GL Painter and mythcenter and X hovers around 1%. Switching to graphite pushes it to average 4-6% BUT the X server goes up to about 6% as well. I bet if I disabled the GL alphapulse used by graphite it would go back to 2% but I haven't tested that.

Nvidia 8400gs, using driver 190.42.

Sorry am the opposite of the subject!

My frontend sits at 14% for a number of seconds then drops to nothing then goes back to 14%

something about 14% almost regardless of CPU frequency. I don't remember
seeing this before.

If there are any developers reading this thread, do you think the issue
justifies its own ticket yet or not? Or are we still convinced it is the
polling on alpha pulse that causes this 14% usage on some, but not all
systems?

Hm, I'm actually surprised I don't see an issue:

MythTV 0.22 (actually, SVN trunk updated and fully recompiled
yesterday afternoon)
GeForce4 440MX
1920x1080 resolution
AthlonXP 2800+ (which I think runs at 2.08 GHz or something)

I'm in the process of rebuilding my system on Slackware 13 ("free
time?" what's that?). I tried with the Qt painter and OpenGL painter,
and both the Terra theme and Blue-Abstract. I get 0% CPU usage under
all the combinations, as reported by htop, while sitting on the main
(first) menu.

Going to the Watch Recordings screen makes the CPU usage jump (heh) to
1% :) (after the screen has finished loading, of course ;-) )

I wish I could leave the OpenGL painter enabled, since it is pretty,
but it's too slow on this card at this resolution.... sometimes...
other times it's great... but that's an issue for another thread... :)
