100% CPU use during playback (0.1-4 and SVN r296) about clementine HOT 12 CLOSED

From xapienz on March 03, 2010 03:29:03

Try hide clementine to tray and see again if it loads cpu.
If the window is open, the cpu load is ~20%. When it is hidden, cpu load is ~2%.

On my machine, when Clementine is not minimized to tray it pegs the CPU. Only about
30% of this goes to Clementine itself, with the remaining 70% (ish) going to X.

Can you still reproduce this with 0.2?

No change to the behaviour in 0.2, unfortunately.

Same problem here, with both 0.1 an 0.2 on Gentoo, using Gnome desktop on my
not-so-fast-anymore laptop. Top reports the processor usage being ~20% for Xorg and
~15% for clementine when idling, ~60-65% for Xorg and ~20-25% for clementine when
playing something. When the main window is hidden, the processor usage drops below 5%

Some of those issues are no longer present on Revision 501 .
Yes, is true that Clementine does consume around ~15% of CPU while Xorg gets its own
~30%-35% of CPU itself while playing, but those are more normal values than what
showed before.

Now, clementine alone gets by now around ~0-10% of CPU when totally idle but with
tracks on its playlist.

And, other thing that I can see, is that the use of RAM of clementine rises to around
+100MB after have played some tracks, but I have not seen it getting on higher levels.

This may somehow depend on either the architecture, or xorg version; I installed
clementine-0.2 on another Gentoo machine, 64-bit this time. Xorg-server is 1.6.5,
using Ati binary drivers: no excessive processor usage with either Fluxbox or KDE4
(stays on about 3%). On the 32-bit laptop where I have the issue Xorg-server is 1.7.6
with savage drivers: processor usage jumps to 100% when playing something, with both
Gnome and KDE4

Oh, an another note: the 32-bit laptop uses pulseaudio, while the the 64-bit desktop
does not. Is this (again) another pulseaudio issue? (I've seriously considered
getting rid of pulseaudio)

I can definitely say that this is not related to sound system. The behaviour is
still the same - when window is not hidden, in eats up a lot (in my case 40% + 50%
by X). When you hide the window, CPU usage falls down.

And it's not pulseaudio-related, since I used it with pulseaudio and without it.
Right now I've removed pulseaudio, and it is still the same.

I use Geforce4 440 MX card with nvidia-96 drivers. I think you should check how
often various redrawings happen.

Also it is unrelated to sound analyzer, since disabling it reduces CPU load for just
few percents.

I can't reproduce this and it's been a while since this was reported. If anyone can
still reproduce this on current trunk then please reopen.

I have this. Here's an approximation of my CPU cosnsumption by Clementine (C) and X

Clementine hidden: C7%; X1%
Clementine shown, no analyzer: C10%; X10%
Clementine shown, bar analyzer: C11%; X22%
Clementine shown, no analyzer, paused: C1%; X1%
Clementine shown, bar analyzer, paused: C3%; X17%

This isn't too drastic, but the issue does come up.

My setup:
i686
clementine 0.4.2
qt 4.6.3
